The XL1583 is a 380KHz fixed frequencyPWM buck (step-down) DC/DC converter,capable of driving a 3A load with high
efficiency, low ripple and excellent line andload regulation. Requiring a minimumnumber of external components, the regulator
is simple to use and include internalfrequencycompensationanda fixed-frequency oscillator.
The RY8337 is a high frequency, synchronous, rectified, step-down, switch-mode converter with internal power
MOSFETs. It offers a very compact solution to provide a 3A continuous current over a wide input supply range,with excellent load and line regulation.
在消费电子、物联网便携设备的硬件设计中,SOT-23 封装 N 沟道 MOS 管是电源通路、负载开关、小型 DC-DC 电路不可或缺的核心元器件。蓝牙耳机充电仓、智能手环、小型移动电源、无线传感模块等产品,普遍存在 PCB 空间狭小、电池供电、长时间待机、高频开关等设计需求,对 MOS 管导通损耗、待机漏电流、开关速度、温稳性都提出严苛标准。
