The NCP1370 is a PWM current mode controller targeting isolatedflyback and non?isolated constant current topologies. The controlleroperates in a quasi?resonant mode to provide high efficiency. Thanksto a novel control method, the device is able to precisely regulate aconstant LED current from the primary side. This removes the needfor secondary side feedback circuitry, biasing and an opto?coupler.The device is highly integrated with a minimum number of externalcomponents. A robust suite of safety protection is built in to simplifythe design. This device supports analog/digital dimming and bothmodes can be combined to enhance dimming precision. The NCP1370has a programmable peak current limit to optimize designcompatibility over a wide range of applications. The controllerfeatures a standby mode with reduced current consumption.
