   产品概述 返回TOPcE2嘉泰姆

The CXSU63219 is a constant frequency, current mode, synchronous step-up switching regulator. It can be used for generating 5V at 400mA from a 3.3V rail or a Li-ion battery.cE2嘉泰姆

High switching frequency minimizes the sizes of inductor and capacitor. Integrated power MOSFETs and internal compensation make the CXSU63219 simple to use and fit the total solution into a compact space.cE2嘉泰姆

For light load current, the CXSU63219 enters into the power-save mode to maintain high efficiency. Anti-ringing control circuitry reduces EMI concerns by damping the inductor in discontinuous mode. The CXSU63219 provides true output disconnect and this allows V_OUT to go to zero volts during shutdown without drawing any current from the input source. The CXSU63219 supports1.8V logic for control.cE2嘉泰姆

The output voltage of CXSU63219-ADJ can be programmed by an external resistor divider, and that of CXSU63219-5.0 is fixed internally on the chip. The device is available in the Green SOT-23-6 package. It operated over an ambient temperature range of -40℃ to +85℃.cE2嘉泰姆
