SC1480A规格书详情
Description
The SC1480A is a single output, constant on-time synchronous-buck, pseudo-fixed frequency, PWM controller intended for use in notebook computers and other battery operated portable devices. Features include high efficiency and fast dynamic response with no minimum on time, a reference input and a buffered REFOUT pin capable of sourcing 3mA. The excellent transient response means that SC1480 based solutions will require less output capacitance than competing fixed frequency converters.
Features
◆ Compatible with DDR & DDR2 memory power requirements
◆ Constant on-time for fast dynamic response
◆ Programmable VOUT based on external reference
◆ VIN range = 1.8V – 25V
◆ DC current sense using low-side RDS(ON) sensing or sense resistor
◆ 3mA reference output buffer
◆ Low power S3 state
◆ Resistor programmable frequency
◆ Cycle-by-cycle current limit
◆ Digital soft start
◆ Output current source-sink capability
◆ Overvoltage/under-voltage fault protection and PGOOD output
◆ Under 10uA typical shutdown current
◆ Low quiescent power dissipation
◆ 14 Lead TSSOP
◆ Industrial temperature range
◆ Integrated gate drivers with soft switching
◆ Efficiency >80
Applications
◆ Notebook computers
◆ CPU I/O supplies
◆ Handheld terminals and PDAs
