AX3301 - PWM Step-Down Controller

General Description

The AX3301 integrates Pulse-Width-Modulation (PWM) control circuit into a single chip.

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

AX3301 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 24V, it is also suitable for the operation via an AC adapter. .

AX3301 PWM Step-Down Controller  GENERAL DESCRIPTION The AX3301 integrates Pulse-Width-Modulation (PWM) control circuit into a single chip. These devise include a reference voltage source, oscillation circuit, error amplifier and etc. AX3301 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%. An enable function, 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. With the addition of an external P-channel Power MOS, a coil, capacitors, and a diode connected externally, these components can function as step-down switching regulators.
