描述 Description
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 PWM operations of the two channels are 180 degree out of phase which can greatly reduce the size and the cost of the input capacitors. Synchronous Buck PWM topology and voltage mode control allow high efficiency operation, fast transient responses, and flexible component selection for easy designs.
特性 Features
◆ 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
Applications
◆ Systems with 4.5V~28V input
◆ LCDTV and PDPTV
◆ Network and telecom systems
◆ Portable devices
