Active4 A MONOLITHIC STEP-DOWN CURRENT SOURCE WITH SYNCHRONOUS RECTIFICATION
Description
General part information
LED2001 Series
LED2001PHR is a 4A monolithic step-down current source with synchronous rectification. This is aN 850KHz fixed switching frequency monolithic step-down DC-DC converter designed to operate as precise constant current source with an adjustable current capability up to 4A DC. The embedded PWM dimming circuitry features LED brightness control. The regulated output current is set connecting a sensing resistor to the feedback pin. The embedded synchronous rectification and the 100mV typical RSENSE voltage drop enhance the efficiency performance. The size of the overall application is minimized due to the high switching frequency and ceramic output capacitor compatibility. Application includes high brightness LED driving, signage, halogen bulb replacement, general lighting.
