Consult factory for inputs up to 16V (Note 2) Operates down to 4.3 Volts Current Mode Control Adjustable output Voltage between 0V and 4V (depends on model, see table 3) Parallelable models available (See Table 3) Synchronizable models available (See Table 3) Enable function available Soft start capable (See Figure 16) Operates at a nominal frequency of 500KHz DESCRIPTION The MHPS series are non-isolated Point of Load switching regulators for high reliability, military, and Space distributed power applications. Fully integrated, these include a buck controller, inductor, and input / output capacitors combined in a single package. They operate from an input voltage of +4.5V to +16V, providing step down power conversion to output voltages as low as 0V. Operating features include output voltage adjust, output current limit, enable, external synchronization and soft start. Some models can also be setup in a parallel configuration to increase output current capability and reduce noise on the input supply. Careful design and layout ensure excellent stability, transient response, and low noise operation. Packaged in compact metal cases, they operate over the full -55C to +125C temperature range.

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 output current available, especially at output Voltages above Vin/2. Minimum available output current is guaranteed to be as specified (3 Amps or 4 Amps, depending on model number) at output Voltages of 2.5V and below, assuming a clean layout. At 3.3V output with a 5V input, reduce available minimum output current by 0.5 Amp. 2. Internal components are rated at +16 Volts maximum, and are therefore properly derated for operation at an input of +5 Volts (minimum of 4.3V). For use at inputs as high as +12 - 15 Volts, please consult factory about your derating requirements for a possible component change to allow properly derated operation. 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 0.4V. 5. Dynamic testing is accomplished at an output load of 1A, and at an output Voltage of 2.5, UOS. 6. Synchronizing pin, if available (see model chart) must be grounded if not used. Consult factory when contemplating use of frequencies above 700 kHz. Pin input impedance is 40K Ohms. 7. Guaranteed by design. 8. All package outline dimensions are in inches. 9. Sequencer section of the Quad Device is rated at 100K RAD. POLs still operate without sequencer. 10. Output Voltage of 1.21V for MHP8566.

However, a slightly more complex compensation of a resistor of value 1.6 kOhms divided by the number of units in parallel, in series with a capacitor of value 3900pF times the number of units in parallel, generally leads to smoother output transitions with less overshoot. Output capacitors should be as shown in Figure 2, one ea CWR29FC227 per regulator. When employing ceramic output capacitors, the simplest compensation is a capacitor whose value is 22nF times the number of units in parallel. This may, however produce an overshoot at turn on. User should check to see that output turn-on, steady state, and transient behavior is acceptable.
