EVB_RT6204GSP

RICHTEK  EVB_RT6204GSP  EVAL BOARD, SYNC STEP DOWN CONVERTER 新

The is an evaluation board to evaluate RT6204 step down RT6204 DC-DC converter. The RT6204 is a 500mA, 60V, high efficiency, synchronous step down DC-DC converter has an input voltage ranging from 5.2V to 60V and a programmable output voltage ranging from 0.8V to 50V. It features current mode control to simplify external compensation and to optimize transient response with a wide range of inductors and output capacitors. High efficiency can be achieved through integrated N-MOSFETs and pulse skipping mode at light loads. With EN pin, power-up sequence can be more flexible and shutdown quiescent current can be reduced to < 3µA. It has cycle by cycle current limit for over current protection against short circuit outputs and user programmable soft-start time to prevent inrush current during start-up. It also includes input undervoltage lockout, output undervoltage and thermal shutdown protection to provide safe and smooth operation in all operating conditions.
