A7235
DC-DC CONVERTER 3.5A 300KHz STEP DOWN DC-DC CONVERTER
DESCRIPTION
FEATURES
The A7235 consists of step-down switching regulator Input voltage : 3.6V to 20V
with PWM control. These devises include a reference Output voltage : 0.8V to VCC
voltage source, oscillation circuit, error amplifier, Duty ratio : 0% to 100% PWM control
internal PMOS and etc.
A7235 provides low-ripple power, high efficiency and external transient characteristics. The PWM control
circuit is able to the duty ratio linearly from 0 up to 100%. The converter is build out soft start function that prevents overshoot and inrush current at startup.
