Conditions
Note 1: The minimum VIN has to meet two conditions: VIN ≥ 2.7V and VIN ≥ VOUT + 0.5V.
2: Reference Feedback Voltage Tolerance applies to adjustable output voltage setting.
3: VR is the output voltage setting.
4: 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. TA, TJ, θJA). Exceeding the maximum
allowable power dissipation causes the device to initiate thermal shutdown.
5: The internal MOSFET switches have an integral diode from the LX pin to the VIN pin, and from the LX 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.
6: The current limit threshold is a cycle-by-cycle peak current limit.
