RZ3111A - PWM Control 3A Step-Down Converter

General Description

RZ3111A consists of step-down switching regulator with PWM control.

These devise include a reference voltage source, oscillation circuit, error amplifier, internal PMOS and etc.

RZ3111A provides low-ripple power, high efficiency, and excellent transient characteristics.

Key Features

  • as low current consumption. Since this converter can accommodate an input voltage up to 40V, it is also suitable for the operation via an AC adapter.

RZ3111A PWM Control 3A Step-Down Converter GENERAL DESCRIPTION RZ3111A consists of step-down switching regulator with PWM control. These devise include a reference voltage source, oscillation circuit, error amplifier, internal PMOS and etc. RZ3111A provides low-ripple power, high efficiency, and excellent transient characteristics. The PWM control circuit is able to the duty ratio linearly form 0 up to 100%. This converter is build out soft start function that prevents overshoot and inrush current at startup. An over current protect function and short circuit protect function are built inside, and when OCP or SCP happens, the operation frequency will be reduced. The operating frequency is decided by outside resistance. An external compensation is easily to system stable.
