TPS92692 Overview
The TPS92692 and TPS92692-Q1 are high accuracy peak current mode based controllers designed to support step-up/down LED driver topologies. The device incorporates a rail-to-rail current amplifier to measure LED current and spread spectrum frequency modulation technique for improved EMI performance. This high performance LED controller can independently modulate LED current using either analog or PWM dimming...
