GM3843A - (GM3842A - GM3845A) HIGH PERFORMANCE CURRENT MODE PWM CONTROLLERS

Download the GM3843A datasheet PDF. This datasheet also covers the GM3842A variant, as both devices belong to the same (gm3842a - gm3845a) high performance current mode pwm controllers family and are provided as variant models within a single manufacturer datasheet.

General Description

GM384XA series is high performance with fixed-frequency current mode PWM controllers.

They are specially designed for off-Line and DC-to-DC converter applications.

They require minimal external components to precisely tailor performance in a wide variety of applications.

Key Features

  • include undervoltage lockouts with hysteresis for both input and reference, cycle-by-cycle current limiting, programmable output deadtime, and a latch for single pulse metering. All these are in a simple DIP-8 or SOP-8 package! GM3842A and GM3844A have UVLO thresholds of 16V (on)/10V(off); GM3843A and GM3845A have UVLO thresholds of 8.4V (on)/ 7.6V (off). GM3842A and GM3843A operate within 100% duty cycle; GM3844A and GM3845A operate within 50% duty cycle. Features Low Start-Up and Operating Cu.

www.DataSheet4U.com Description GM384XA series is high performance with fixed-frequency current mode PWM controllers. They are specially designed for off-Line and DC-to-DC converter applications. They require minimal external components to precisely tailor performance in a wide variety of applications. GM384XA series includes a trimmed oscillator for precise duty cycle control, a temperature-compensated reference, high gain error amplifier, a current-sensing comparator, and a high-current totem pole output for driving a power MOSFET. On-chip protection features include undervoltage lockouts with hysteresis for both input and reference, cycle-by-cycle current limiting, programmable output deadtime, and a latch for single pulse metering.
