The CXSU63135 is a PWM/PFM, high-efficiency, and stepup DC-DC converter with an integrated LDO input switch for dual mode application. During battery mode operation, the CXSU63135 acts as synchronous rectifier and step-up DC-DC converter with a fixed or adjustable output voltage. When the VIN pin sense 5V input voltage, the CXSU63135 is switched to LDO operation mode, maintaining the constant output voltage. The input voltage ranges from 0.6 V to 4.5V for step-up DC-DC converter. The start-up is guaranteed at 1V and the device operates down to 0.6V. When the device is at LDO operating mode, the suitable output voltage 3.3V and loading current 500mA for maximum power consumption are guaranteed. The CXSU63135 is suited for dual mode and portable battery powered appliance with low-battery detector. In dualmode applications, the CXSU63135 draws power from any available 5V USB connection and reverts to battery power when the USB power is removed.
