The HC3066 is a compact, 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 1V makes HC3066 suitable for 1 to 4 battery cells applications of providing up to 300mA output current. The 20μA low quiescent current together with high efficiency maintains long battery lifetime. The output voltage is set with two external resistors.
