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, […]
What is a charge pump and why is it useful? part 1
Converting an available DC source to a lower or higher voltage is a very common challenge in circuits. One option for the high-to-low conversion is to use a low-dropout regulator (LDO), but how can an LDO easily transform a lower voltage into a higher one? The answer for AC voltages is well-known: use a transformer, […]
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 […]
100-V no-opto flyback regulator delivers up to 24 W, 1-kV Output
Linear Technology Corporation announces the H-grade versions of the LT8304/-1, monolithic flyback regulators with guaranteed operation for junction temperatures as high as 150°C. By sampling the isolated output voltage directly from the primary-side flyback waveform, the part requires no opto-coupler or third winding for regulation. The LT8304 operates over a 3V to 100V input voltage […]

The PI3525-00-LGIZ is a 5V output regulator, supplying up to 20A, packaged […]
Monolithic flyback regulator for junction temperatures up to 150°C.
Linear Technology Corporation announces the H-grade version of the LT8303, a monolithic flyback regulator with guaranteed operation for junction temperatures as high as 150°C. By sampling the isolated output voltage directly from the primary-side flyback waveform, the part requires no opto-isolator or third winding for regulation. The LT8303 operates over a 5.5V to 100V input […]
Step-down 40-to-240-A switching regulator trips breaker for overvoltage/overtemperature faults
Linear Technology Corporation introduces the LTM4636-1, a 40A to 240A scalable step-down µModule switching regulator. The part incorporates protection circuitry that trips a circuit breaker in the event of overvoltage or overtemperature fault conditions to protect itself, the PCB and loads such as high current low voltage processors, FPGAs, GPUs and ASICs. An output crowbar function […]
Tiny LDOs generate less than 6.5 µVrms noise at 250 mA full load
STMicroelectronics’ LDLN025 Low-Dropout (LDO) voltage regulators deliver best-in-class noise performance in relation to outputcurrent and footprint, generating less than 6.5µVrms noise at 250mA full load with an outline of just 0.63mm x 0.63mm.
