Description

The KB3301 is a small, high efficiency, and low voltage step-up DC/DC converter with an Adaptive Current Mode PWM control loop, includes an error amplifier, ramp  generator, comparator, switch pass element and driver in which providing a stable and high efficient operation over a wide range of load currents. It operates in stable waveforms without external compensation.

The low start-up input voltage below 0.8V makes KB3301 suitable for 1 to 4 battery cells applications of providi up to 300mA output current. The 500KHz high switching rate minimized the size of external components. Besides,the 14A low quiescent current together with high effic-iency maintains long battery lifetime.

The KB3301 is available in small package SOT-26 and SOT89-5
