NCL30000 Product details

Description

Pin Name Function 1 MFP The multi-function pin is connected to the internal error amplifier.By pulling this pin below the Vuvp threshold, the controller is disabled.In addition, this pin also has an over voltage comparator which will disable the controller in the event of a fault.2 COMP The COMP pin is the output of the internal error amplifier.A compensation network is connected between this pin and ground to set the loop bandwidth.Normally this bandwidth is set at a low frequency (typ

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 CrM 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 mV to minimize power dissipation in the external sense resistor. To support the environ.
