IR3887MTRPBF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

The IR3887 is an easy-to-use, fully integrated dc - dc Buck regulator. The onboard PWM controller and OptiMOS™ FETs with integrated bootstrap diode make IR3887 a small footprint solution, providing high-efficient power delivery. Furthermore, it uses a fast Constant On-Time (COT) control scheme, which simplifies the design efforts and achieves fast control response.\r
\r
The IR3887 has an internal low dropout voltage regulator, allowing operations with a single supply. It can also operate with an external bias supply, extending the operating input voltage (PVin) range from 2.0 V to 17 V.\r
\r
The IR3887 is a versatile regulator, offering programmable switching frequency from 600 kHz to 2 MHz, four selectable current limits, four selectable soft-start time, Forced Continuous Conduction Mode (FCCM) and Diode Emulation Mode (DEM) operation.\r
\r
It also features important protection functions, such as pre-bias start-up, thermally compensated current limit, over voltage and under voltage protection, and thermal shutdown to give required system level security in the event of fault conditions.

简介

IR3887MTRPBF属于集成电路（IC）的稳压器-DC-DC开关稳压器。由制造生产的IR3887MTRPBF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。
