High Efficiency Step-up DC/DC Converter

The PT1302 is a compact, high efficiency, and low voltage Step-up DC/DC converter with an Adaptive Current Mode PWM control loop. It comprises of an error Amplifier a ramp generator, a PWM Comparator a Switch pass element and driver. It provides stable and high efficient operation over a wide range of load currents. It operates in stable waveforms without external compensation. It is suitable for 1~4 battery cells applications to provide up to 800mA output current. The 500KHz high switching rate reduces the size of external components. Besides, the 25A low quiescent current together with high efficiency maintains long battery lifetime. The output voltage is set with two external resistors. Both internal 2A Switch and 300mA driver for driving external power devices (NMOS or NPN) are provided.
