Description
The STK73907-T is an original Sanyo thick-film hybrid integrated circuit (IC) functioning as a self-excitation type feedback control off-line switching regulator module. Utilizing high-efficiency Power MOSFET switching elements rather than traditional bipolar transistors, it supports a higher oscillator frequency which minimizes the size requirement for external pulse transformers and capacitors.
Key Features & Specifications:
- Function: Self-Excitation Feedback Control Off-Line Switching Regulator
- Output Power Rating: 180W
- Internal Elements: Integrated Power MOSFETs, driver circuits, and error amplifiers on a single module
- Protection: On-chip overcurrent protection (OCP) circuit
- Substrate Technology: Sanyo IMST (Insulated Metal Substrate Technology) acts as a built-in electromagnetic shield for low-noise operation
- Applications: Commonly found in CRT/CTV television power supplies and legacy office automation equipment power bricks
- Manufacturer: Sanyo Electric Co., Ltd.
A pristine New-Old-Stock (NOS) component critical for component-level power supply repair and structural restorations of legacy CRT monitors and vintage electronic hardware.
