1 / 5 page TS3404 1-5 2003/12 rev. A TS3404 PWM Buck Controller Pin assignment: 1. Out 2. Vcc 3. Comp. 4. FB 5. SCP 6. 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. 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. The TS3404 is offered in DIP-8 and SOP-8 package. Features PWM buck control circuit Operating voltage can be up to 27V Under voltage lock out (UVLO) protection Soft start (SS) circuit Short circuit Protection (SCP) Variable oscillator frequency 300KHz (max) 1.25V voltage reference Output Pin Descriptions Name Description Output PWM Output Vcc Supply Voltage Comp. Feedback Loop Compensation FB Voltage Feedback SCP Short Circuit Protection SS Soft Start CT Timing Capacitor Gnd Ground Applications LCD Monitor xD-ROM, xDSL product DC to DC converters in computers Backlight inverter Ordering Information Part No. Operating Temp. (Ambient) Package TS3404CS SOP-8 TS3404CD -20 ~ +85 oC DIP-8 Absolute Maximum Rating Supply Voltage VCC 28 V Amplifier Input Voltage VI 20 V Collector Output Voltage VO Vcc~1.0V V Source Current ISOURCE 200 mA Sink Current ISINK 200 mA Operating Junction Temperature Range TJ -20 ~ +150 oC Storage Temperature Range TSTG -65 ~ +150 oC Lead Temperature 1.6mm(1/16”) from case for 10Sec.
