general description
the hs601 is a 1.2mhz constant frequency, current mode pwm step-up converter. it can supply 3.3v output voltage at 100ma from a single aa cell. the device integrates a main switch and a synchronous rectifier for high efficiency without an external schottky diode. a switching frequency of 1.2mhz allows the use of tiny, low profile inductors and
ceramic capacitors. the current mode pwm operation with internal compensation provides excellent line and load transient characteristics. the hs601 features pulse skipping mode operation at light loads to avoid unacceptable ripple voltage.
the hs6601is offered in a low profile (1 mm) small
6-pin sot23 package.
