The NSIP3266-Q1 H-bridge transformer driver provides a simple solution for designing isolated power supplies. The device drives the primary coil of the transformer with a voltage range from 6.5V to 26V. The transformer’s secondary-to-primary turn ratio defines the output voltage, allowing selection of virtually any isolated output voltage. The NSIP3266 features adjustable switching frequency from 100 kHz to 1MHz with an external resistor, which provides the flexibility to optimize either efficiency or external component size. A Fault output is asserted when the device detects an overtemperature or overcurrent condition. In addition, the device features a low-power mode to reduce the overall supply current to 0.7mA (typ) when the driver is disabled. The NSIP3266 is available in HMSOP8 package with operating temperature range from -40°C to 125°C.
