LM2694MT Datasheet PDF - TI

●The LM2694MT is a step-down Switching Regulator features all of the functions needed to implement an efficient, buck bias regulator capable of supplying 0.6A to the load. This buck regulator contains an N-channel buck switch. The feedback regulation scheme requires no loop compensation, results in fast load transient response and simplifies circuit implementation. The operating frequency remains constant with line and load variations due to the inverse relationship between the input voltage and the on-time. The valley current limit results in a smooth transition from constant voltage to constant current mode when current limit is detected, reducing the frequency and output voltage, without the use of foldback. Additional features include VCC undervoltage lockout, thermal shutdown, gate drive undervoltage lockout and maximum duty cycle limiter.
