1.3 Specification

The TPS92622SOPQ1EVM is set up for a default output current of 150 mA per channel. External shunt resistors on RES pin are leveraged to share output current and dissipate power out of the device. This EVM 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 different dimming modes. This EVM can be used to verify diagnostic and protective functions. Additionally, the LED open detection can be disabled to avoid false open diagnostic during low-dropout operation.
