SC2544
Not recommended for new designs.
The SC2544 is a high performance dual PWM controller. It is designed to convert a wide ranged input voltage down to two independent output rails. The SC2544 support “peel off ” tracking for the two outputs at start up which means the two outputs ramp up together till the one with lower output level reaching the regulation.
Features
- Independent dual-outputs
- “Peel off “start up tracking Independent dual-outputs
- Wide input voltage range: 4.5V~28V
- Adjustable output voltage down to 0.75V
- Flexible power sequencing with enable and power good output
- Synchronous Buck topology with voltage mode control
- Out of phase operation to reduce cost of input capacitor
- 10V internal regulator for gate driver to deliver high efficiency
- Programmable switching frequency: 100kHz~300kHz
- Full protection: UVLO, OVP and programmable OCP
- No need for current sense resistor
- Low shutdown current (100nA typical)
- 24 lead TSSOP and MLPQ packages
- Fully WEEE and RoHS Compliant
- Systems with 4.5V~28V input
- LCDTV and PDPTV
- Network and telecom systems

In 1885, Karl Benz, a German engineer, invented the first functional automobile. Over the past 130 years, automobiles have evolved considerably. Semtech is proud to be a part of the automotive technology journey and is aiding this evolution by offering key technologies that contribute to the advancement of safety, reliability and performance of automobiles. In commemoration of the inventor’s birthday, November 25, we take a look at some key automotive applications for integrated circuits (IC), and highlight Semtech’s contribution (or participation) to their implementation.
