The LTC3826IG-1#TRPBF is a high efficiency, low noise dual output synchronous step-down switching regulator controller with integrated MOSFETs from Analog Devices. It is part of the LTC3826 family of regulators. The LTC3826IG-1#TRPBF is offered in an 8-pin DUB or 6-pin TSSOP package. It features an input voltage range from 4.5V to 34V, and an output voltage range from 0.5V to 21V. The controller features adjustable switching frequency from 100 kHz to 2 MHz and can deliver up to 20A output current with an efficient peak current mode control scheme. The integrated dual N-channel MOSFETs minimize external part count and provide fast switching speeds. It operates in constant frequency peak current mode with dual pulse-width modulation (PWM) output, allowing for excellent line and load regulation. Other features include automatic skip cycle, programmable Soft Start, overcurrent protection, short-circuit protection, and Thermal Shutdown.
