TL3842D-8 General Description

Featuring in the TL284x and TL384x series, the TL3842D-8 is a versatile control integrated circuit catering to off-line or DC-to-DC fixed-frequency current-mode control designs. Equipped with an array of internal circuits such as undervoltage lockout (UVLO) with a meager start-up current, a finely trimmed precision reference at the error amplifier input, and logic for ensuring latched operation, this IC offers a comprehensive solution with minimal external component requirements. The presence of a pulse-width modulation (PWM) comparator for current-limit control, along with a totem-pole output stage designed for high-peak current needs, makes it a reliable choice for driving N-channel MOSFETs while maintaining a low off-state level

Key Features

Fast Response Time and Low Noise
Improved Efficiency and Reduced Heat Generation
Robust Immunity Against EMI and RFI Interference
Precise Temperature Monitoring and Control

Safe Operating Area and Current Limiting
Redundant Power Path for High Availability
