NCL30000 Power Factor Corrected Dimmable LED Driver The NCL30000 is a switch mode power supply controller intended for low to medium power single stage power factor (PF) corrected LED Drivers. The device is designed to operate in critical conduction mode (CrM) and is suitable for flyback as well as buck topologies.

Constant on time CrM operation is particularly suited for isolated flyback LED applications as the control scheme is straightforward and very high efficiency can be achieved even at low power levels. These are important in LED lighting to comply with regulatory requirements

and meet overall system luminous efficacy requirements. In CrM, the
CASE 751
switching frequency will vary with line and load and switching losses are low as recovery losses in the output rectifier are negligible since

the current goes to zero prior to reactivating the main MOSFET switch. MFP VCC The device features a programmable on time limiter, zero current Comp DRV detect sense block, gate driver, trans-conductance error amplifier as Ct GND CS ZCD well as all PWM control circuitry and protection functions required to (Top View) implement a CrM switch mode power supply. Moreover, for high efficiency, the device features low startup current enabling fast, low loss charging of the V

CC capacitor. The current sense protection threshold has been set at 500 mV to minimize power dissipation in the external sense resistor. To support the environmental operation range 8 of Solid State Lighting, the device is specified across a wide junction L0000 temperature range of −40C to 125C. ALYW G
