Supply 5V4A Travel Charger IC | charger IC CX7010

CX7010 | 5V4A Travel Charger IC | charger IC CX7010 PSR-precision switching power supply control chip overview CX7010 is a high precision off-line switching power supply circuit, used in low-power AC / DC charger and adapter. CX7010 uses a 6 SOT23 package with a maximum power of 25W. CX7010 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 sampling resistor R7 set. 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. CX7010 in constant current mode works in PFM state, working in constant voltage mode PWM state, reduced frequency at light loads. CX7010 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. CX7010 has a shake-frequency function, can provide better EMI performance. Features CX7010 | 5V4A Travel Charger IC | charger IC within 5% of the full voltage range constant voltage accuracy, current precision of 5% using primary side feedback control, eliminating the need for external optocoupler and TL431 can set the output current value Power Built PSR constant current control built-adaptive peak current control built-in primary inductance compensation can be externally adjusted to compensate power line voltage drop on the built-in soft-start leading edge blanking (LEB) function-by-cycle current limit protection (OCP) less voltage protection (UVLO), overvoltage protection (OVP), VDD voltage clamping protection Over temperature protection applications SOT23-6 package phone charger PDA, digital camera battery charger TV, PC auxiliary power can replace linear regulators, RCC Power CX7010 | 5V4A Travel Charger IC | charger IC Shenzhen-Core Micro Technology Co., Ltd.
