Notes:

1. All minimum and maximum specifications apply across the recommended operating conditions. Typical values apply at

nominal supply voltages and an operating temperature of 25 °C unless otherwise stated.

2. Operation at minimum voltage dependent upon loop conditions and dc-dc converter configuration.
