TL3842P General Description

Offering a wide input voltage range of 8 to 35 volts and a fixed operating frequency of 50 kHz, the TL3842P is a reliable pulse-width modulation (PWM) controller IC designed for switch-mode power supply applications. Its adjustable output voltage and current limiting capabilities provide flexibility for power supply designs, making it a versatile choice for different system requirements. The integration of essential functions such as a voltage reference, error amplifier, ramp generator, oscillator, pulse control, and output driver stages simplifies the overall design and implementation process. Moreover, the inclusion of a built-in frequency compensation network ensures stability and accuracy in power supply designs. Packaged in an 8-pin dual in-line package (DIP), the TL3842P offers easy installation on printed circuit boards, contributing to its convenience and usability in diverse applications
