A high-voltage tolerant output driver for use in a switching regulator is provided herein. The driver allows the switching regulator to regulate supply voltages that exceed device breakdown limits for the process technology from which the high-voltage tolerant output driver is fabricated. Unregulated supply voltages can vary over a wide range. The regulator only needs two intermediate voltages.

High-voltage tolerant output driver

A current mode logic (CML) flip flop includes a first CML latch and a second CML latch. A plurality of pull-up switches are responsive to a reset signal. Outputs of the first and second CML latches are pulled up to a supply voltage through the pull-up switches. The first CML latch includes a first pull-up isolation switch driven by the reset signal for resetting the latch.
