NCP1404 Series Product Preview 350 m A 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 ponents, this series allow a simple means to implement highly efficient converters for powering up portable equipment up to 350 m A 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 m V steps can be manufactured. Features - Low Start- Up Voltage of 0.8 V - PWM Oscillator Frequency of 600 k Hz at 20% Accuracy - High Efficiency 85% at IOUT = 200 m A, VIN = 2.5 V, VOUT = 3.3 V - Output Current up to 350 m A at VIN = 2.5 V, VOUT = 3.3 V - Duty...
