Overview
The UM1663S is a highly integrated LED driver IC capable of driving 10 WLEDs in series. It is composed of a current mode boost converter integrated with a 38V/1A power switch. The UM1663S supports a wide input voltage range from 2.8V to 5.5V and runs at a fixed frequency of 1MHz. The LED current is set via an external resistor and the feedback voltage is regulated to 200mV. During operation, the LED current is controlled by the duty cycle of the SHDN input signal, which determines the feedback reference voltage. The UM1663S can modify dimming to support 64-step pulse dimming. The UM1663S also has internal overvoltage protection setting to prevent the output from exceeding the absolute maximum ratings during open LED conditions. It is available in GreenSOT23-6 package and operates over an ambient temperature range of -40°C to +85°C.
