LM36274EVM, Evaluation Module for LM36274 Regulated Charge Pump Inverter

Beschreibung

• LM36274EVM, Evaluation Module is designed to evaluate the LM36274 integrated LED driver and LCD bias supply. The backlight boost provides the power to bias four parallel LED strings with up to 29V total output voltage and up to 30 mA/string. The 11-bit LED current is programmable via the I2C bus and/or controlled via a logic-level PWM input. Each LED string can be independently enabled/disabled to provide zone dimming capabilities. The LCD bias boost provides the power to both a positive LDO and an inverting charge pump. An auto-sequencing feature provides a programmed delay from positive to negative bias activation with additional programmable voltage slew-rate control
