. SS 7. CT 8. Gnd Supply Voltage Range 3.6V to 27V Output Driving Current 200mA Oscillator Frequency up to 300KHz 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.
