Preliminary
LINEAR INTEGRATED CIRCUIT
PWM CONTROL 3A
STEP-DOWN CONVERTER
„ DESCRIPTION
The UTC P4596 consists of 3A step-down switching regulator
with PWM control which includes a reference voltage source,
oscillation circuit, error amplifier, internal PMOS and etc.
The UTC P4596 can provide low-ripple power, high efficiency,
and excellent transient characteristics and an enable function, an
over current protect function and a short circuit protect function
are built inside, And the PWM control circuit can vary the duty
ratio linearly from 100 down to 0%. This converter also includes
an error amplifier circuit as well as a soft-start circuit that prevents
overshoot at startup. These ICs can work as step-down switching
regulators with the addition of an internal P-channel Power MOS,
a coil and a diode connected externally. They provide such
outstanding features: low current consumption. It is also suitable
for the operation via an AC adapter because this converter can
accommodate an input voltage up to 40V.
„ FEATURES
* Input voltage：8V~40V
* Duty ratio：0%~100% PWM control
* Enable with Soft-Start function
* Oscillation frequency can be set by outside resistance
* Current Limit, SCP and OTP
