CHARACTERISTICS
Parameters
The minimum V
Reference Feedback Voltage Tolerance applies to adjustable output voltage setting.
V
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
allowable power dissipation causes the device to initiate thermal shutdown.
The internal MOSFET switches have an integral diode from the L
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.
