General Description

The LM3495 is a PWM buck regulator which implements a unique emulated peak current mode control.

This control method eliminates the switching noise which typically limits current mode operation at extremely short duty cycles and high operating frequency.

The switching frequency is programmable between 200 kHz and 1.5 MHz, and can also be synchronized to an external clock.
