Original authentic CX7151 Charger Power Module IC

Factory Direct original authentic CX7151 Charger Power Module IC Prudential core micro-factory supply genuine original factory direct high precision CX7151 PSR switching power supply chip overview CX7151 is a high precision off-switching power supply circuit, used in low-power AC / DC Chargers and adapters. CX7151 maximum output power of 6W, using SOP8 / DIP8 package. CX7151 using primary sampling for accurate constant current control, eliminates the need for general application of the optocoupler and TL431. In constant current mode, the output power by CS pin external sense resistor Rs settings. Under constant pressure mode, multiple operating modes of the chip can guarantee higher overall conversion efficiency. In addition, the chip built-in cable drop compensation, thus making good load regulation. CX7151 in constant current mode works in PFM state, working in constant voltage mode PWM state, reduced frequency at light loads. CX7151 provides a power soft start function and various protection functions can be self-recovery, including by-cycle current limit protection (OCP), VDD over voltage protection (OVP), VDD over voltage clamp, undervoltage protection (UVLO), overtemperature protection. CX7151 has a shake-frequency function, can provide better EMI performance. Within the original genuine factory direct supply module CX7151 charger IC Prudential core features of micro-factory supply the full voltage range of 5% constant precision, 5% of current precision using primary side feedback control, eliminating the need for external optocoupler and TL431 can be set given current value and output power Built PSR constant current control built-in adaptive peak current control built-in primary inductance compensation can be externally adjusted line drop compensation (with proportional increase resistor R5 R6 improve line up) Built-in soft-start power-edge blanking (LEB) function by-cycle current limit protection (OCP) voltage protection (UVLO), overvoltage protection (OVP), VDD voltage clamping protection CX7151 charger genuine original factory direct supply module IC Cheng Core micro-factory supply applications mobile phone charger PDA, digital camera battery charger TV, PC auxiliary power can replace linear regulators, RCC power Shenzhen-Core Micro Technology Co., Ltd.
