1.3 Specification

The TPS92621Q1EVM is set up for a default output current of 250 mA. External shunt resistors on RES pin are leveraged to share output current and dissipate power out of the device. The device has an enable selection through EN pin, when the EN signal is low, the device is in sleep mode with ultra low quiescent current, which can help to save system-level current consumption in applications. By applying external voltage duty cycle signal on either SUPPLY or PWM pins, the device is able to operate in SUPPLY or PWM dimming modes. The device can be used to verify diagnostic and protective functions, the LED open detection can be disabled when the voltage applied on DIAGEN pin is less than the logic-low voltage threshold to avoid false open diagnostic during low-dropout operation.
