LTC3612IUDC#PBF, Linear Technology
Step-Down (Buck) Regulators, Micropower Buck Regulators, Linear Technology
Linear Technology
presents a range of micropower monolithic step-down buck converters these are intended for applications that need to increase efficiency at light loads. These devices produce low standby quiescent currents when in burst mode. They can be used in applications such as high voltage power conversion, battery powered, Automotive, distributed power and Industrial power systems.
Switching Voltage Regulators, Linear Technology
Linear Technology
product series of synchronous and non-synchronous internal switching regulator ICs offer high efficiency plus a wide input voltage range and switching frequencies up to 4MHz.
The controllers span over several types of configurations from buck (step-down), boost (step-up), buck-boost, forward, Isolated, Inverting and flyback controllers. The Flyback, Forward and Isolated Controllers primary and secondary side provide a solution to help replace the DC/DC bricks that get used in back-plane power conversion.

MAX17244ETERB+, Maxim
The MAX17244 high-efficiency, synchronous step-down DC-DC converter with integrated MOSFETs operates over a 3. 5V to 36V input voltage range with 42V input transient protection. The device can operate in dropout condition by running at 98% duty cycle. This converter delivers up to 2. 5A and generates fixed output voltages of 3. 3V/5V, along with the ability to program the output voltage between 1V to 10V. The MAX17244 uses a current-mode control architecture. The device can operate in the pulse-width modulation (PWM) or pulse-frequency modulation (PFM) control schemes.
