DC1207A - LT3504 Demo Board | Quad Buck, 5.4V ≤ VIN ≤ 40V, Vout1 - Vout4 = 5V/3.3V/2.5V/1.8V @ 1A Each
The demo circuit 1207A is a quad current mode PWM stepdown DC/DC converter featuring the LT®3504. The demo circuit is designed for 5V, 3.3V, 2.5V and 1.8V outputs from a 5.4V to 40V input. The current capability of each channel is up to 1A. Individual soft-start and current limit for each output as well as synchronous function simplify the complex design of quad-output power converters.
Each converter is synchronized to either a common external clock input or a resistor programmable 250kHz to 2.2MHz internal oscillator. Programmable frequency allows optimization between efficiency and external component size. Each output can be independently disabled using its own RUN/SS pin.
