Notes:
10. In the event of more than one fault/warning condition occurring, the higher priority condition will take precedence.
For example ‘Excessive coil current’ and ‘Out of regulation’ occurring together will produce an output of 0.9V on the STATUS pin.
These STATUS pin voltages apply for an input voltage to V IN of 7.5V < V IN < 60V. Below 7.5V the STATUS pin voltage levels reduce and
therefore may not report the correct status. For 5.4V < V IN < 7.5V the flag pin still reports any error by going low. At low V IN in Boost and
Buck-boost modes an over-current status may be indicated when operating at high boost ratios – this due to the feedback loop increasing
the sense voltage.
For more information see the Application Information section about Flag/Status levels.
11. Flag is asserted if V SHP < 1.5V or V SHP > 2.5V
12. GATE is switched to the supply voltage V AUX for low values of V AUX (5V ≤ V AUX ≤ ~12V). For V AUX > 12V, GATE is clamped internally to prevent
it exceeding 15V.
13. GATE is switched to PGND by an NMOS transistor
14. If t ON exceeds t STALL , the device will force GATE low to turn off the external switch and then initiate a restart cycle. During this phase, ADJ is
grounded internally and the SHP pin is switched to its nominal operating voltage, before operation is allowed to resume. Restart cycles will be
repeated automatically until the operating conditions are such that normal operation can be sustained. If t OFF exceeds t STALL , the switch will
remain off until normal operation is possible.
