NCL30000 Datasheet | onsemi

features a programmable on time limiter, zero current detect sense block, gate driver, trans-conductance error amplifier as well as all PWM control circuitry and protection functions required to implement a Cr M switch mode power supply. Moreover, for high efficiency, the device features low startup current enabling fast, low loss charging of the VCC capacitor. The current sense protection threshold has been set at 500 m V to minimize power dissipation in the external sense resistor. To support the environmental operation range of Solid State Lighting, the device is specified across a wide junction temperature range of - 40C to 125C. Features - Very Low 24 m A Typical Startup Current - Constant On Time PWM Control - Cycle-by-Cycle Current Protection - Low Current Sense Threshold of 500 m V - Low 2 m A Typical Operating Current - Source 500 m A/Sink 800 m A Totem Pole Gate Driver - Reference Design for TRIAC and Trailing Edge Line Dimmers - Wide Operating Temperature Range - No Input Voltage Sensing Requirement - Enable Function and Overvoltage Protection - These Devices are Pb-Free, Halogen Free/BFR Free and are Ro HS pliant Typical Applications - LED Driver Power Supplies - LED Based Down Lights - mercial and Residential LED Fixtures - TRIAC Dimmable LED Based PAR Lamps - Power Factor Corrected Constant Voltage Supplies http://onsemi.
