Product Preview
350 mA PWM/PFM Step-Up
DC-DC Converter with Low
Battery Detector
The NCP1404 series are monolithic PWM/PFM step–up DC to DC
converters which can automatically change operation mode from
PWM to PFM at light loads to improve efficiency at light loads. With
only four external components, this series allow a simple means to
implement highly efficient converters for powering up portable
equipment up to 350 mA loading.
Additionally, this series is featured with a Low Battery Detector to
monitor battery voltage. The NCP1404 device series are available in
space–saving TSOP–6 package with five standard regulated output
voltages. Additional voltages that range from 1.8 V to 5.0 V in
100 mV steps can be manufactured.
