General Description

The TS3404 integrates Pulse Width Modulation (PWM) control circuit into a single chip, and makes simple work out of implementing a complete control and protection scheme for a DC-DC step-down converter.

The TS3404 provides simple feedback loop compensation, 1.25V reference output, error amplifier, adjustable oscillator, soft start, under voltage lock out (UVLO), short circuit protection(SCP) circuitry, and push pull output circuit.

The TS3404 is design for adjustable switching frequency by trimming time capacitor (CT), during low supply voltage situation, the under voltage lock out (UVLO) makes sure that the output are off until the internal circuit operates normally.
