TI - Smallest, highest efficiency 6-A step-down SWIFT DC/DC converter
Texas Instruments builds upon its popular SWIFT family of power management integrated circuits with a new 6-A converter that is the industry’s smallest and most efficient. The new TPS54618 monolithic synchronous switcher with two integrated 12-milliohm FETs provides 95-percent efficiency and low operating current to 2.95-V to 6-V point-of-load designs used in DSP- and FPGA-based communications, test and medical equipment.
LDOs from Diodes Incorporated extend battery life
Characterised by low dropout voltage and low quiescent current, the latest linear regulators from Diodes Incorporated suit low power handheld product design where extending battery life is a key design criteria. Dual fixed output devices, the 150mA AP7312 and 300mA AP7332 exhibit respective dropouts of 150mV and 300mV and typical quiescent current ratings of only 60µA.
Fairchild Semiconductor’s PFC/PWM Controller Provides Higher Efficiency in Dual-Switch Flyback Topologies
Power engineers, especially those involved in All-In-One (AIO) PC power, Slim Pack PC adapters, LCD TV and LED lighting designs, require a dual switch flyback topology that provides the higher efficiency and increased energy savings required by government regulations – something that LLC or single flyback solutions cannot provide. Developed to answer this need, Fairchild Semiconductor’s FAN6920MR, an integrated critical mode PFC and quasi-res...
3A Output, 2MHz Synchronous Buck-Boost DC/DC Converter Offers Low Noise Operation & Extended Run Time from Batteries or Supercapacitors
Linear Technology LTC3113, a synchronous buck-boost converter that delivers 3A of output current from a nominal 3.3V power source, Li-Ion/Polymer battery or up to 1A from dual cell alkaline/NiCad/NiMH batteries. The LTC3113's 1.8V to 5.5V input range and 1.8V to 5.5V output range provides a regulated output from an input voltage above, below or equal to the output. The LTC3113 is also an ideal regulator solution to maximize the energy available f...
IR - MOSFET Chipset Tailored for Cost Sensitive DC-DC Applications
International Rectifier has introduced the IRF6708S2 and IRF6728M 30 V DirectFET® MOSFET chipset tailored for cost sensitive 19 V input synchronous buck applications. The IRF6708S2 Small Can and IRF6728M Medium Can devices reduce component count by 30 percent to drastically reduce overall system cost. The new DirectFET MOSFETs feature low charge and on-state resistance RDS(on) to minimize conduction and switching losses. The IRF6728M also featur...
Linear constant current driver from Diodes Incorporated provides versatile control for LED applications
The AL8400 linear LED driver controller from Diodes Incorporated has been designed to tightly regulate a wide variation of high brightness LED currents via an external transistor. Suiting a broad range of LED chains in illumination, indication or signage systems, the controller can directly operate from 2.2V to 18V and will drive either N-channel MOSFET or NPN Bipolar transistors.
Single Inductor High Efficiency Synchronous Buck-Boost DC/DC Controller
Linear Technology announced the LTC3789, a very high efficiency (up to 98%) synchronous buck-boost DC/DC controller that operates from input voltages above, below or equal to the regulated output voltage. High power circuits that step-up and-down typically rely on transformers or two DC/DC converters, one for step-up (boost) and the other for step-down (buck) conversion. The LTC3789 operates using a single inductor with 4-switch synchronous rect...
