Introduction

AI Translation

TPS92520-Q1 is a monolithic dual-channel synchronous buck LED driver with a wide operating input voltage range of 4.5V to 65V, capable of independently driving two strings of series-connected LEDs. The TPS92520-Q1 implements adaptive on-time average current mode control, designed to be compatible with shunt FET dimming technology and LED matrix manager-based dynamic beam headlights. The adaptive on-time control provides a near-constant switching frequency, configurable from 100kHz to 2.2MHz. Inductor current sensing and closed-loop feedback enable better than ±4% accuracy across wide input voltage, output voltage, and ambient temperature ranges.

This high-performance LED driver supports individual LED current modulation using analog dimming or PWM dimming. Programming the 10-bit IADJ value via SPI achieves a linear analog dimming ratio greater than 16:1. PWM dimming of the LED current is achieved either by directly modulating the corresponding UDIM input pin with the desired duty cycle, or by enabling the internal PWM generator circuit. The PWM generator converts the 10-bit PWM register value to the corresponding duty cycle by comparing it against a programmable digital counter.

The TPS92520-Q1 integrates advanced SPI-programmable diagnostics and fault protection features, including: cycle-by-cycle current limiting, bootstrap undervoltage protection, LED open circuit, LED short circuit, thermal warning, and thermal shutdown. An on-board 10-bit ADC samples critical input parameters required for monitoring and diagnosing system health.

The TPS92520-Q1 is available in a thermally enhanced 32-pin HTSSOP package measuring 8.1mm x 11mm, with a 2.75mm x 3.45mm top-exposed thermal pad and bottom-exposed thermal pad.
