Sync buck regulators step down inputs to just 0.6 V
Intersil, a subsidiary of Renesas Electronics Corporation (TSE: 6723), today introduced five synchronous buck regulators that step-down 12V rails to point-of load inputs as low as 0.6V for MCUs, FPGAs, memory and peripheral I/Os. The newest members of the ISL850xx family consist of the ISL85014, ISL85012, ISL85009, ISL85005A and ISL85005 buck regulators. They deliver 14A, […]
100-V bridge power stage module targets half-bridge and full-bridge DC-DC converters
ON Semiconductor has launched the FDMF8811, the industry’s first 100 V Bridge Power Stage module for half-bridge and full-bridge isolated dc-dc converters. The 25 A-rated device integrates a 120 V driver IC, a bootstrap diode, and two highly efficient power MOSFETs in a PQFN-36 package. The FDMF8811 reduces the board area required for dc-dc converter […]
Controller handles dual dc/dc switching circuits simultaneously
A new Digitally Enhanced Power Analog (DEPA) product for DC-DC power conversion is now available from Microchip Technology Inc. The single-chip solution controls DC-DC converters and is capable of accepting a high voltage input (up to 42V) while simultaneously regulating a wide output voltage range (300 mV to several hundred volts, depending on topology). The […]

What is a charge pump and why is it useful? (Part 1)
It’s a very common challenge in circuits to need to convert an available DC source to a lower or higher voltage. For the high-to-low conversion, one option to use a low dropout regulator (LDO), but how to easily transform a lower voltage into a higher one? For AC voltages, the answer is well-known: use a […]
Avoiding mobile device brownouts
By Chuck Wong, Intersil, a Renesas Company With the ever-increasing performance of mobile application processors and GPUs, the need for a buck-boost regulator to stabilize the Li-ion battery supply-voltage terminals is becoming more and more important. Buck-boost regulators prevent brownout (a condition where power is briefly lost) by boosting the supply voltage during the notching […]
