Descrizione

Traduzione AI

TLD5542-1 is a synchronous MOSFET H-bridge DC/DC controller with integrated protection features and SPI interface. The design enables driving high-power LEDs with maximum system efficiency and a minimal external component count. TLD5542-1 supports both analog and digital (PWM) dimming. The switching frequency is adjustable from 200kHz to 700kHz and can be synchronized to an external clock source. The built-in programmable spread-spectrum switching frequency modulation and forced continuous current regulation mode improve overall EMI performance. In addition, the current-mode regulation scheme provides a stable regulation loop with compact external compensation components. The adjustable soft-start function limits inrush current and voltage overshoot during startup. TLD5542-1 is designed for demanding automotive environments.
