    SC81230H是一款高效同步降压转换器，仅需少量外部元件，便于应用于紧凑型设计。该器件工作输入电压范围为3V至17V，典型开关频率为1.2MHz。内置功率MOSFET，可支持高达3A的连续输出电流。


    Descriptions

    SC81230H is a high - efficiency synchronous buck converter

    with few external components, making it easy to use in

    compact applications. The device operates with input

    voltages from 3V to 17V and has a typical switching

    frequency of 1.2MHz. It integrates power MOSFETs and can

    support up to 3A continuous output current.

    SC81230H can operate in a large duty cycle to offer a low

    input-to-output voltage differential when the VIN is equal to

    VOUT.

    The device also features low quiescent current and PSM

    mode operation to maximize efficiency at light load. With

    PSM mode and low quiescent current during standby or light

    load, the device can further prolong battery life and is

    suitable for battery-powered applications.

    The device adopts a constant on-time control mode with

    internal compensation, which features excellent load

    transient performance and supports low equivalent series

    resistance output capacitors such as ceramic (MLCC)

    capacitors.

    SC81230H offers multiple protection features. These

    include input under - voltage protection, cycle - by - cycle

    peak current limitation, and thermal shutdown protection

    with auto - recovery.
