Dual Output PSU for HV Input Evaluation Board User's Manual

Overview

TopologyBuck Converter
Input voltage440 V
Output 115 V / 0.15 A

Description

The NCP10970BGEVB evaluation board is a non−isolated buck topology converter which provides adjustable output voltage up to 16 V and fixed linear output voltage 5 V. Input voltage range is from ~30 Vrms up to 440 Vrms. The board is also ready for DC input voltage up to 620 V. Nominal output current of the board is 150 mA. This current is divided between switcher output and LDO output, i.e. when LDO provides 100 mA of output current, there is 50 mA on switcher output. The NCP10970B1 is SOIC−16 power management IC combines HV switcher, LDO, internal circuitry for creating the input voltage for LDO in very effective way and internal comparator circuitry. The switcher works in a DCM mode for better efficiency, EMI and surge robustness. To ensure low no−load standby power and good efficiency at light load, the device is equipped with a skip mode operation. A dedicated comparator circuitry provides a means to instruct the external control section that an over−temperature or over−current point has been reached. The comparator input is biased by a precise constant current source and output is an open−drain type. The speed of comparator is driven by a voltage value on STBY pin.
