NOTES:
1. Most internal components are rated at +10 Volts maximum with some as high as 16V, and are therefore properly
derated for operation at a nominal input of +5 Volts. For use at higher input voltages, please consult factory about
your desired operation voltage and your derating requirements for a check of possible component changes.
2. Internal series switch is self protected and is rated to conduct 4.5 Amps minimum. However, limitations on
internal components plus the characteristics of PWM operation conspire to reduce further the minimum available
output current, especially at output Voltages above Vin/2. Minimum available output current is guaranteed to be
as specified at output Voltage of 2.5 V down to 1.21 V, assuming a clean layout. At output Voltages below 1.21
V, maximum output current may reduce by up to 1 Amp, depending on actual output Voltage, and load regulation
may degrade slightly (up to 1%). At 3.3 V output with a 5 V input, output current reduces by 0.5 A from the value
specified at 2.5 V out.
3. Microsemi does not at this time have a MIL-PRF-38534 qualified radiation hardness assurance program.
4. If not used, or when on, Enable pin should be pulled up to a logic one (2.5V min, 7V max) through a resistor of no
more than 5K Ohms. Voltage on this pin to disable operation needs to be less than 0.13V.
5. Testing is accomplished at an output load of 1A, and at an output Voltage of 2.5V and an input of 5V unless
otherwise specified. Only the specification with post irradiation limits are tested after radiation exposure.
6. Synchronizing pin, if available (see model chart) must be grounded if not used. Consult factory when
contemplating use of frequencies above 580 kHz. Pin input impedance is 40K Ohms.
7. All package outline dimensions are in inches.
8. Consult factory for operation at output voltages below 1.0V. Also see Figure 10.
9. Minimum input voltage is guaranteed by line regulation test.
10. Performed at a DLA approved facility.
11. Tested per MIL-PRF-38534.
