LM3310中文资料具有集成运算放大器和闸极脉冲调制开关的升压 PWM直流/直流转换器数据手册TI规格书

描述 Description

The LM3310 is a step-up DC/DC converter integrated with an Operational Amplifier and a gate pulse modulation switch. The boost (step-up) converter is used to generate an adjustable output voltage and features a low RDSON internal switch for maximum efficiency. The operating frequency is selectable between 660kHz and 1.28MHz allowing for the use of small external components. An external soft-start pin enables the user to tailor the soft-start time to a specific application and limit the inrush current. The Op-Amp is capable of sourcing/sinking 135mA of current (typical). The gate pulse modulation switch can operate with a VGH voltage of 5V to 30V. The LM3310 is available in a low profile 24-lead WQFN package.

简介

LM3310属于集成电路（IC）的稳压器-DC-DC开关稳压器。由TI制造生产的LM3310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。
