MC34063EC中文资料DC-DC转换器控制电路数据手册ST规格书

描述 Description

The MC34063A/E series is a monolithic control circuit which delivers the main functions for DC-DC voltage converting.

The device contains an internal temperature compensated reference, comparator, duty cycle controlled oscillator with an active current limit circuit, driver and high current output switch. Output voltage is adjustable through two external resistors with a 2% reference accuracy.

Employing a minimum number of external components, the MC34063A/E device series is designed for step-down, step-up and voltage-inverting applications.

特性 Features

• Output switch current in excess of 1.5 A
• 2 % reference accuracy
• Low quiescent current: 2.5 mA (typ.)
• Operating from 3 V to 40 V
• Frequency operation to 100 kHz
• Active current limiting

简介

MC34063EC属于集成电路（IC）的稳压器-DC-DC开关稳压器。由制造生产的MC34063EC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。
