SC2544
Product inactive. Information on this page is for reference only.
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.
功能
- 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
