PF7900S мікросхема живлення SOP8

Контролер живлення Корпус: SOP-8 Маркування: PF7900 S 9V to 27V Input Current Mode Boost Controller The PF7900 is a wide-input voltage boost controller which can be operated from 9V to 27V. The special dimming input helps to synchronize this device with multi-channel current matching ICs or MOSFETs for LED applications such as LED backlight or LED lighting. PF7900 integrated the curren mode PWM controller with a high driving capability MOSFET driver, over current protection, and input/output over voltage protection in a SOP-8 package to minimize the PCB size as well s the component counts. The adjustable frequency setting helps users to select the optimized operation frequency. Wide Input Range: 9V to 27V Adjustable Switching Frequency Setting Current Mode Control 300mV Current Sensing Reference Over Current Protection Over Temperature Protection Output Over Voltage Protection Input Over Voltage Protection PWM Dimming Input Новая почта Ін-тайм УкрПочта
