SC2542
Product inactive. Information on this page is for reference only.
SC2542 is a high performance dual PWM controller. It is designed to convert a widely ranged battery rail down to two independent output rails. The PWM operation of the two channels are 180 degrees out of phase which can greatly reduce the size and the cost of the input capacitors.
Features
- Independent dual-switcher-outputs
- Integrated 5V standby output with over 50mA capability
- Wide input voltage range: 6.5V ~ 28V
- Adjustable output voltage down to 0.75V
- Light load efficiency enhancement
- Programmable skip mode operation
- 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 standby operating current (200μA typical)
- Low shut down current (100nA typical)
- 28 lead TSSOP package with exposed die pad (EDP)
- Fully WEEE package and RoHS Compliant
- Notebook computer system power
- Systems with 6.5V ~ 28V input
- Network and telecom systems
- Other portable devices
