ACTIVE OUTPUT DISCHARGE SWITCH

Each buck regulator in the ADP5014 integrates a discharge

switch from the switching node to ground. This switch is turned on

when its associated regulator is disabled, which helps discharge

the output capacitor quickly. The typical value of the discharge

switch is 85 Ω for Channel 1 to Channel 4.

THERMAL SHUTDOWN

If the ADP5014 junction temperature exceeds 150°C, the thermal

shutdown circuit turns off the IC except for the internal linear

regulator. Extreme junction temperatures can be the result of

high current operation, poor circuit board design, or high ambient

temperature. A 15°C hysteresis is included so that the ADP5014

does not return to operation after thermal shutdown until the

on-chip temperature falls below 135°C. When the device exits

thermal shutdown, a soft start is initiated for each enabled channel.
