原裝現(xiàn)貨 CJ9311T6 長晶1.2MHz同步升壓轉(zhuǎn)換器
INTRODUCTION
The CJ9311 devices provide a power supply solution for products powered by either a one-cell, two-cell, or three-cell alkaline, NiCd or NiMH, or one-cell Li-ion or Li-polymer battery. The boost converter is based on a fixed frequency, pulse-width-modulation (PWM) controller using a synchronous rectifier to obtain maximum efficiency, which contains an internal NMOS switch and PMOS synchronous rectifier. The maximum peak current in the boost switch is typically limited to a value of 1.1A.
A switching frequency of 1.2MHz minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors.
The current mode PWM design is internally compensated, reducing external parts count. Anti-ringing control circuitry reduces EMI concerns by damping the inductor in discontinuous mode. In shutdown, VOUT and VIN are connected, which allows the input battery to be used for backup power. The device features low shutdown current less than 1μA.
