NCP10970 Datasheet - ON Semiconductor

NCP10970 High-Voltage Switcher

Pin No. Pin Name Function Description 1 SOURCE The switcher ground This pin is connected to the buck source/inductor junction and grounds the switcher circuitry. The dissipated heat of the transistor is conducted out through this pin. 2 VCC Supplies the switcher section The switcher VCC v.

High-Voltage Switcher with Linearly Regulated Output NCP10970 The NCP10970 includes a high voltage switcher, linear regulator and a dedicated comparator circuitry. The switcher is suitable for building output voltage up to 16 V (adjustable by resistor divider on FB pin) protected against short circuit. Dedicated internal circuitry prevents continuous conduction mode (CCM) operation improves the surge robustness, efficiency and EMI. In no load/light load condition.
