NCP1051 - Monolithic High Voltage Gated Oscillator Power Switching Regulator

Download the NCP1051 datasheet PDF. This datasheet also covers the NCP1050 variant, as both devices belong to the same monolithic high voltage gated oscillator power switching regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

Pin Pin (SOT 223) (PDIP 8) Function 1 1 VCC 2 2 Control Input 4 3, 7, 8 Ground

This is the positive supply voltage input.

During startup, power is supplied to this input from Pin 5.

Key Features

  • an active startup regulator circuit that eliminates the need for an auxiliary bias winding on the converter transformer, fault detector and a programmable timer for converter overload protection, unique gated oscillator configuration for extremely fast loop response with double pulse suppression, power switch current limiting, input undervoltage lockout with hysteresis, thermal shutdown, and auto restart fault detection. These devices are available in economical 8.
  • pin dual.
  • in.

NCP1050, NCP1051, NCP1052, NCP1053, NCP1054, NCP1055 Monolithic High Voltage Gated Oscillator Power Switching Regulator The NCP1050 through NCP1055 are monolithic high voltage regulators that enable end product equipment to be compliant with low standby power requirements. This device series combines the required converter functions allowing a simple and economical power system solution for office automation, consumer, and industrial products. These devices are designed to operate directly from a rectified AC line source. In flyback converter applications they are capable of providing an output power that ranges from 6.0 W to 40 W with a fixed AC input of 100 V, 115 V, or 230 V, and 3.0 W to 20 W with a variable AC input that ranges from 85 V to 265 V.
