Electronic Specifier takes a look at the top power products to have been released in March.

1. The MAX17577 and MAX17578 from Maxim Integrated Products are small, high-efficiency synchronous inverting DC/DC step-down converters. As Maxim’s first 60V inverting DC/DC converters with integrated level shifters, the company claim these devices save up to 72% of board space by reducing component count by half while using 35% less energy than the closest competitive solutions.

Both ICs reduce size, heat, and cost, while simplifying the design of negative output voltage rails needed for analog signals within intelligent IoT devices found in factory automation, building automation and communications systems.

As network edge devices expand with Artificial Intelligence capabilities, designers must reduce the solution size and heat generation. They seek solutions that are more efficient, creating less heat and use less board space, saving time and cost.

The MAX17577 and MAX17578 integrate level shifting circuitry to reduce component cost and count by as much as 50% while reducing component area to 60mm², a 72% advantage in board space over competitive solutions. These synchronous inverting converters protect against input voltage transients with the industry’s widest input voltage range from 4.5V to 60V, thus increasing system robustness in harsh environments.

2. Power Integrations has announced a new member of its LinkSwitch-TN2 AC/DC converter family. The new LNK3207 ICs facilitate higher-power offline buck converter designs for appliances and industrial applications by increasing the available output current from 360 to 575mA, while also reducing BOM count.

Silvestro Fimiani, product marketing manager at Power Integrations, said: “These new LinkSwitch-TN2 ICs are pin-to-pin compatible with previous generations, making it simple for customers to upgrade to higher-power designs. A high-current buck converter can be created using a minimal number of easily available components while saving at least one diode over previous solutions.”

The LNK3207 AC/DC converter ICs increase the available current by 60% while also delivering greater than 80% efficiency and no-load consumption of less than 30mW. Each monolithic LinkSwitch-TN2 IC incorporates a 725V power MOSFET, oscillator, on/off control for high efficiency at light load, a high-voltage switched current source for self-biasing, frequency jittering, fast (cycle-by-cycle) current limit, hysteretic thermal shutdown, and output and input overvoltage protection circuitry.

The new LinkSwitch-TN2 ICs target mass-market appliances such as washers, dryers and coffee makers, which benefit from their design simplicity. They are also suitable for sensor-based devices that require low power such as home security cameras and smart thermostats, as well as metering and IoT installations. Devices are available in three packages, PDIP-8C, SMD-8C and SO-8C, for design flexibility. The SMD-8C package is ideal for high-temperature ambient 85/105°C applications.

3. The AC/DC modules of the series PCMAT150 S24 from MTM Power are suitable as a decentralised power supply for both industrial and railway applications. From wide AC/DC (90 to 264 VAC) input range for the worldwide use in industrial networks, a 12 VDC or 24 VDC output voltage is generated.

The contact-cooled devices have a power good signal as well as an active PFC. Further features are an operating temperature of -40 to +70°C, remote control and 150% power boost.

The design of the isolation coordination acc. to overvoltage category OV 3 enables the use in applications with high transients as e.g. energy technology. For the use on rail vehicles, the devices were tested according to the standards of EN 50 155 and EN 50 121-3-2 / EN 50 121-4. In compliance with the conditions of the railway regulations the units can be used on railway vehicles on the 400/230 VAC internal on-board train power system, in track-side applications and in stationary railway systems.

4. CUI has announced the addition of two 75W and 100W high-density, quarter brick DC/DC series to its isolated DC/DC converter line. These new compact products utilise the latest technology, allowing for a much smaller footprint while maintaining high operating efficiency up to 94%. These converters are additionally designed to meet the latest regulatory requirements for EN 62368-1.

These DC/DC converter models offer a wide input in a more compact quarter brick package, making it well suited for railway, data, telecom, and industrial applications where a large amount of power is needed in a smaller footprint.

5. Toshiba Electronics has underlined its strength in power management by announcing the introduction of its new TCR5RG series. These Low Drop-Out (LDO) voltage regulators cover an output voltage range of 0.9-5.0V, thereby giving them scope to be employed in a wide variety of potential applications.

They have a100dB ripple rejection ratio (when operating at a 1kHz frequency). This has been achieved through the combination of a wide-gap internal circuit topology, an integrated high-speed operational amplifier supporting low noise operation, plus low-pass filtering.

The expansive LDO series comprises a total of 45 different devices, all of which are housed in WCSP4F packages that take up only minimal PCB space. They support a maximum output current of 500mA and have a 5μV (typical) output voltage noise, with a ±1.5% output voltage accuracy at voltages between 1.8Vand2.8V (going to ±1.8% for voltages above 2.8V) and a chip temperature range of -40°C to +85°C.
