Simple analogue PWM control for DC/DC converters

Simple analogue PWM control for DC/DC converters
Claimed to be the industry’s first devices to combine 40V operation and PMBus communication interfaces, Microchip has introduced its latest Digitally Enhanced Power Analogue (DEPA) controllers. The MCP19118 and MCP19119 provide simple yet effective analogue PWM control for DC/DC synchronous buck converters up to 40V and offer the same configurability as a digital MCU.

Switching regulator integrates LDOs for accurate tracking

Switching regulator integrates LDOs for accurate tracking
A 400mA, 40V step-down switching regulator with dual tracking LDO outputs has been released by Linear Technology. Operating from a VIN range of 4.3-40V with transient protection to 60V, the LT3668 is particularly suitable for automotive and industrial applications. Up to 400mA can be delivered by the internal 600mA switch and distributed to the combined loads of the primary output and both of the tracking LDOs.

Buck-boost converter extends usable life of Li-ion batteries

Buck-boost converter extends usable life of Li-ion batteries
Designed to prolong battery life in single-cell Li-ion battery applications where the output voltage is within the battery voltage range, the XC9306 converter has been released by Torex Semiconductor. When discharged, a Li-ion battery's operating voltage declines to the point that it can no longer power it's load. The synchronous buck-boost converter boosts the output voltage of the battery, extending it’s usable life.
