Description
A push-pull transformer driver with low noise and EMI, the SN6505ADBVR was created especially for tiny, isolated power supply. It uses a DC power source ranging from 2.25 V to 5 V to drive low-profile, center-tapped transformers. By slew rate controlling the output switch voltage and using spread spectrum clocking, ultra-low noise and EMI are made possible (SSC). The oscillator and gate drive circuit of the SN6505ADBVR provide the complementary output signals needed to control ground-referenced N-channel power switches. The device has two 1-A Power-MOSFET switches to ensure that it can start up even when under a lot of loads. When using several transformer drivers or for precise placement of switcher harmonics, the switching clock can also be given externally. A 1.7 A current limiter, an under-voltage lockout, a thermal shutdown, and break-before-make circuits are some of the internal protection measures.
The SN6505ADBVR has a soft-start feature that reduces high inrush current when large load capacitors are powered up. For applications that need to limit emissions but also demand higher efficiency and smaller transformer size, the SN6505ADBVR includes a 160 kHz internal oscillator. Small 6-pin SOT23/DBV packages of the SN6505ADBVR are available. The operating characteristics of the device are described over a temperature range of -55°C to 125°C.
