Typical Operating Characteristics

(VIN = -48V, AGND = DGND = 0, UVLO = open circuit, VENABLE = +3.3V, RLOAD = 1.8k

Ω, TA = +25°C, unless otherwise noted.)

ELECTRICAL SPECIFICATIONS (continued)

(VIN = -48V, AGND = DGND = 0, UVLO = open circuit, VENABLE = +3.3V, and TA = -40°C to +85°C, unless otherwise noted. Typical

values are at TA = +25°C.)

Note 1: Minimum ENABLE low pulse width required to unlatch fault condition.

Note 2: The delay from IOUT falling below the zero-current threshold until FAULT is latched low and VOUT is disabled.

Note 3: The time from an output overcurrent or short-circuit condition until the output goes into current limit.

Note 4: The time from VOUT falling until FAULT is asserted low. FAULT is not latched for Power-Not-Good condition.

Note 5: When the device goes into thermal shutdown, the output is disabled and FAULT is latched low.
