The LTC3839IUH#TRPBF part is a synchronous, step-down, monolithic dual-channel DC/DC switching regulator controller from Analog Devices, Inc. This device is designed to provide high efficiency, pulse-width modulation control of two independent output voltages. It features a dedicated power supply channel, overvoltage, undervoltage, and IPS mode protection, a programmable soft-start, and is housed in a small, 16-lead (3mm x 4mm) TSSOP package. The device also includes a precision internal oscillator, allowing for flexible device operation without the need for an external clock circuit.
