Drive Capability

The transformer driver is designed for low-power push-pull converters with input and output voltages in the range of 2.25V to 5.5V. While converter designs with higher output voltages are possible, care must be taken that higher turns ratios do not lead to primary currents that exceed the specified current limits of the device.
