AX3165/A
consists of step down switching regulator with PW M control. These devise
include a reference voltage source, oscillation circuit, error amplifier, internal PMOS and
etc.
AX3165/A
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. An external
compensation is easily to system stable; the low ESR output capacitor can be used.
With th
e 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 SOP 8L with
exp osed pad package, providing such outstanding features as low current consumption.
Since this converter can accommodate an input voltage up to 55 V, it is also suitable for the
operation via an AC adapter.
