  • The NCP1370 is a PWM current mode controller targeting isolated flyback and non−isolated constant current topologies. The controller operates in a quasi−resonant mode to provide high efficiency. Thanks to a novel control method, the device is able to precisely regulate a constant LED current from the primary side. This removes the need for secondary side feedback circuitry, biasing and an opto−coupler. The device is highly integrated with a minimum number of external components. A robust suite of safety protection is built in to simplify the design. This device supports analog/digital dimming and both modes can be combined to enhance dimming precision. The NCP1370 has a programmable peak current limit to optimize design compatibility over a wide range of applications. The controller features a standby mode with reduced current consumption.
