TPS92602 Evaluation Module (EVM)

Overview

TopologyBoost Converter
Input voltage5.86-40 V
Output 175 V / 1 A

Description

The TPS92602-Q1 is a dual-channel LED driver. The basis for each independent driver is a peak-currentmodeboost controller. Each controller has a current feedback loop with high-side current-sensing shuntand a voltage-feedback loop with an external resistor-divider network. Each controller has twoindependent feedback loops, a current-feedback loop with high-side current-sensing shunt and a voltagefeedbackloop with an external resistor-divider network. The controller delivers a constant output voltageor a constant output current. The connected load determines whether the board is regulating a constantoutput current (if current set point is reached earlier than voltage set point) or a constant output voltage (ifthe voltage set point is reached first, for example in an open-load condition).Each controller supports all typical topologies like boost, boost to battery, SEPIC, or flyback.Uses for the high-side PMOS FET driver are for PWM dimming of the LED string and for cutoff in case ofan external short circuit to GND in order to protect the circuit.
