FAN5307数据手册集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF

描述 Description

General Description
The FAN5307, a high efficiency low noise synchronous PWM current mode and Pulse Skip (Power Save) mode DC-DC converter is designed for battery-powered applications. It provides up to 300mA of output current over a wide input range from 2.5V to 5.5V. The output voltage can be either internally fixed or externally adjustable over a wide range of 0.7V to 5.5V VIN by an external voltage divider. Custom output voltages are also available. Contact a Fairchild sales representative for customized output voltage options.

简介

FAN5307属于集成电路（IC）的稳压器-DC-DC开关稳压器。由制造生产的FAN5307稳压器 - DC-DC 开关稳压器DC-DC 开关稳压器 PMIC（电源管理集成电路）产品族中的产品是元器件级设备，用于需要稳定 DC 输入电压和/或将其转换为不同幅度的输出电压的应用。这些器件与称为“控制器”PMIC 的类似产品的区别在于集成了主开关元件，设备提供的电力会通过该元件。
