SC483規(guī)格書詳情
Description
The SC483 is a dual output constant-on synchronous buck PWM controller intended for use in notebook computers and other battery operated portable devices. Features include high efficiency and a fast dynamic response with no minimum on time. The excellent transient response means that SC483 based solutions will require less output capacitance than competing fixed frequency converters.
Features
◆ Constant on-time for fast dynamic response
◆ Programmable VOUT range = 0.5 – VCCA
◆ VBAT Range = 1.8V – 25V
◆ DC current sense using low-side RDS(ON) sensing or sense resistor
◆ Resistor programmable frequency
◆ Cycle-by-cycle current limit
◆ Digital soft-start
◆ Separate PSAVE option for each switcher
◆ Over-voltage/Under-voltage fault protection
◆ 10μA Typical shutdown current
◆ Low quiescent power dissipation
◆ Two Power Good indicators
◆ 1 Reference (2 system DC accuracy)
◆ Integrated gate drivers with soft switching
◆ Separate enables
◆ 28 Lead TSSOP
◆ Industrial temperature range
◆ Output soft discharge upon shutdown
Applications
◆ Notebook computers
◆ CPT I/O supplies
◆ Handheld terminals and PDAs
◆ LCD monitors
◆ Network power supplies
