Shenzhen Mingjiada Electronics Co., Ltd.——Long term supply of TI (SN6505ADBVR) low noise, 1A, 160kHz transformer driver for isolated power supplies.

Product Details:

The SN6505ADBVR is a low noise, low EMI push-pull transformer driver designed for small isolated power supplies.The SN6505ADBVR drives thin, mid-tap transformers from a 2.25V to 5V DC supply. Ultra-low noise and EMI are achieved through slew rate control of the output switching voltage and spread spectrum clocking (SSC).

Part Number: SN6505ADBVR

Package: SOT-23-6

Type: Transformer Driver

Product Diagram:

The SN6505ADBVR contains two 1A supply MOSFET switches to ensure proper startup under heavy load conditions, and a soft-start feature to prevent high inrush currents during power-up of large load capacitors. The device has a 160kHz internal oscillator for applications that require a significant reduction in radiation.
