P4596

UNISONIC TECHNOLOGIES CO., LTD P4596 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  ORDERING INFORMATION Ordering Number Lead Free Halogen Free P4596L-SH2-R P4596G-SH2-R Package HSOP-8 HSOP-8 Packing Tape Reel P4596G-SH2-R (1)Packing Type (2)Package Type (3)Green Package (1) R: Tape Reel (2) SH2: HSOP-8 (3) G: Halogen ...
