1. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by

characterization and are not production tested.

2. Test Condition: VIN = 5V, FB forced above regulation point (0.6V), no switching, and power MOSFET gate charging current not included.

3. Minimum On-Time required to maintain loop stability.

4. Compliance to limits is assured by design.

L=1µH, Cout=22µF, TA = +25°C

Figure 5. Efficiency vs Load, VOUT = 1.2V

Figure 6. Efficiency vs Load, VOUT = 0.6V

Figure 7. Efficiency vs Load, VOUT = 3.3V

Figure 8. VOUT Regulation vs Load, VOUT = 1.2V

Typical operating conditions at 25°C, VIN = 5V, TJ = -40 to +125 °C, unless otherwise specified. Boldface limits apply across the

operating temperature range (-40°C to +125°C) (Cont.)
