LT3922 2A同步升壓LED驅動器
Linear Technology/Analog Devices LT3922 2A Synchronous Step-Up LED Drivers are monolithic converters with a fixed-frequency, peak current control and PWM dimming for a string of LEDs. The LT3922 can operate in boost, buck or buck-boost modes. The LED current is programmed by an analog voltage or the duty cycle of pulses at the CTRL pin. The LT3922 will maintain ±2% current regulation through an external sense resistor over a wide range of output voltages.
