The minimum V IN has to meet two conditions: V IN ≥ 2.7V and V IN ≥ V OUT + 0.5V.
Reference Feedback Voltage Tolerance applies to adjustable output voltage setting.
V R is the output voltage setting.
The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable
temperature and the thermal resistance from junction to air (i.e. T A , T J , θ JA ). Exceeding the maximum
allowable power dissipation causes the device to initiate thermal shutdown.
The internal MOSFET switches have an integral diode from the L X pin to the V IN pin, and from the L X pin
to the GND pin. In cases where these diodes are forward-biased, the package power dissipation limits
must be adhered to. Thermal protection is not able to limit the junction temperature for these cases.
The current limit threshold is a cycle-by-cycle peak current limit.
