TPS61500 具有集成 3A、40V 电源开关的高亮度 LED 驱动器

TPS61500 描述

The TPS61500 is a monolithic switching regulator with integrated 3-A, 40-V power switch. It is an ideal driver for high brightness 1-W or 3-W LED. The device has a wide input voltage range to support application with input voltage from multi-cell batteries or regulated 5-V, 12-V power rails. The LED current is set with an external sensor resistor R3, and the feedback voltage that is regulated to 200-mV by current mode PWM (pulse width modulation) control loop, as shown in the typical application. The device supports analog and pure PWM dimming methods for LED brightness control. Connecting a capacitor to the DIMC pin configures the device to be used for analog dimming, and the LED current varies proportional to the duty cycle of an external PWM signal.
