LM2696 Datasheet (National Semiconductor) - Constant On Time Buck Regulator

LM2696, Constant On Time Buck Regulator

The LM2696 is a pulse width modulation (PWM) buck regulator capable of delivering up to 3A into a load.

The control loop utilizes a constant on-time control scheme with input voltage feed forward.

This provides a topology that has excellent transient response without the need for compensation.
