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 […]

New Family of 20-A 48-V ZVS Buck Regulators target PoL apps
The PI3525-00-LGIZ is the latest addition to the Cool-Power ZVS Buck Regulator Portfolio with a 48V (30-60Vin) input. The PI352x is a higher current offering to the existing PI354x portfolio enabling scalable power options for 48V Direct to point of Load (PoL) applications. 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. To ensure high accuracy and sensitivity the LDLN025 is designed to supply ultra-smooth and stable voltage to precision ICs like ADCs, VCOs, […]
40-V switching regulators take on heads-up displays and other automotive apps
Exar Corporation today announced a new AEC-Q100 qualified family of 40V switching regulators for automotive applications such as infotainment head units and Advanced Driver Assistance Systems (ADAS). The XR76203-Q, XR76205-Q and XR76208-Q are 3A/5A/8A synchronous step-down regulators designed to provide a wide 5.5V to 40V input voltage range and an adjustable output voltage down to […]
Choosing an integration level for power supply functions
Since the first application of the wheel, an element of all practical engineering projects has been the make-or-buy decision. The issue is fractal, arising at every level of the design hierarchy: For any given function, at some level of abstraction, you’ll choose to switch between make and buy. But the decision doesn’t hinge on a […]

Designing adjustable voltage SMPS – I am planning to make an adjustable voltage SMPS. How do I […]
When should I use an LDO versus a switching regulator?
Both switchers and LDOs have their place in power distribution, as each has special attributes. With few exceptions, every electronic circuit needs at least one well-regulated, accurate, stable dc power rail at 12, 5, 3.3 V, or even at 1 V, and many systems need five, ten or more such rails. This power must come […]
40-A power POL regulator features high thermal conduction
Linear Technology Corporation introduces the LTM4636, a 40A step-down µModule switching regulator with 3D construction for quicker heat dissipation and cooler operation in a small package. By stacking its inductor on top of a 16mm x 16mm BGA package, the LTM4636 benefits from the exposed inductor as a heat sink, permitting direct contact with airflow from […]
