General Description

The SG348xG series of current-mode PWM con

Overview

Product Specification BiCMOS Green-Mode PWM Controllers SG3842G/ 3843G/ 3844G/ 3845G start-up current has been reduced to 5uA, and the minimum operating current has been reduced to 5mA.

Each SG384xG has a slew rate controlled high current totem pole output, ideally suited for driving a power MOSFET while keeping EMI low.

The current-sense propagation delay is typically 50ns, resulting in significantly more effective constant power protection.

Key Features

384x series pin-to-pin compatible Linearly decreasing PWM frequency Burst-mode at low/zero load 5uA start-up current 5mA operating current Vcc over voltage protection Cycle-by-cycle current limiting Zero cross-conduction Slew rate controlled high current totem pole output Fast current sense propagation delay Under voltage lockout (UVLO) with hysteresis.
