Recommended Operating Conditions

(4)

Supply Voltage VIN .......................... 4.5V to 24V

Output Voltage VOUT.............. 0.8V to VIN*DMAX

(5)

Operating Junction Temp. (TJ). -40°C to +125°C

Thermal Resistance

(6)

θJA

θJC

QFN-20 (3mmx5mmx1.6mm)... 46 ...... 10... °C/W

Notes:

1) Exceeding these ratings may damage the device.

2) For additional details on EN pin’s ABS MAX rating, please

refer to the “Enable Control” section on page 14.

3) The maximum power dissipation is a function of the maximum

junction temperature TJ (MAX), the junction-to-ambient

thermal resistance θJA, and the ambient temperature TA. The

maximum continuous power dissipation at any ambient

temperature is calculated by PD (MAX) = (TJ (MAX)-TA)/θJA.

Exceeding the maximum allowable power dissipation will

produce an excessive die temperature, causing the converter

to go into thermal shutdown. Internal thermal shutdown

circuitry protects the device from permanent damage.

4) The device is not guaranteed to function outside of its

operating conditions.

5) In practical design, the minimum VOUT is limited by the

minimum on-time. To allow a margin, a 50ns on-time is

recommended for calculating. To set the output voltage above

5.5V, please refer to the application information on page 17.

6) Measured on JESD51-7, 4-layer PCB.
