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. An
Oscillation frequency is 300KHz
Current limit, Short Circuit Protect (SCP) and
Thermal Shutdown protection
Built-in internal SW P-channel MOS
Available in SOP8 Package
over current protect function and short circuit protect APPLICATION
function are built inside, and when OCP or SCP
happens, the operation frequency will be reduced.
Also, an internal compensation block is built in to
minimum external component count.
With the addition of an internal P-channel Power MOS,
a coil, capacitors, and a diode connected externally,
these ICs can function as step-down switching

regulators. They serve as ideal power supply units for
portable devices when coupled with the SOP8 TYPICAL APPLICATION
package, providing such outstanding features as low
current consumption. Since this converter can
accommodate an input voltage up to 20V, it is also
suitable for the operation via an AC adapter.
The A7235 is available in SOP8 package.
