LM2696 Datasheet PDF - National

General Description

●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 compen sation. The input voltage feed forward ensures that a constant switching frequency is maintained across the entire VIN range.
