TP1000 Micro-Precision Constant Voltage/Constant Current Primary Feedback Controller

TP1000 High Precision Constant Voltage/Constant Current Primary Feedback Controller

Overview

TP1000 is a high-performance AC/DC power supply controller that adopts frequency modulation (PFM) mode, and the flyback circuit works in the off-state.

in freewheeling current mode (DCM). The chip has built-in various fault protection circuits, and the reliability is extremely high.

TP1000 provides accurate constant voltage/constant current (CV/CC) controller without optocoupler, secondary control circuit and loop compensation circuit

Achieving stable and reliable system operation can greatly simplify the design of low-power CV/CC power converters. The device uses innovative

The unique control technology can provide extremely tight output voltage and current regulation.

The TP1000 controller has high working efficiency and low no-load power consumption, with a typical value of 100mW@220Vac. Suitable for wide input

CV/CC power converters and adapters with output power ranging from 0.5W-10W, 3-12Vdc.
