Description The AP9151AM by API Technologies is a non-isolated Point of Load switching regulator 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 4.6 to 6.0 V, providing step down power conversion to output voltages as low as 1 V (or lower). Operating features include output voltage adjust, output current limit, and enable; Some models have external synchronization and soft start functionality. Additionally, some models can also be setup in a parallel configuration to increase output current capability and reduce ripple on the input and output supplies. Careful design and layout ensure excellent stability, transient response, and low noise operation. Packaged in a compact metal case, they operate over the full -55oC to 125oC temperature range. The AP9151AM Point of Load (POL) switching regulators are more efficient than competitive POLs. (See Table 5.)

At the time of publication of this datasheet, API Technologies/Marlborough did not have a MIL-PRF-38534 qualified radiation hardness assurance program. 2. If not used, or when on, Enable pin should be pulled up to a logic one (2.0 V min, 6 V max) through a resistor of no more than 5 K Ohms. Voltage on this pin to disable operation needs to be less than 1.45 V. 3. Testing is accomplished at an output load of 1 A, and an output Voltage of 2.5 V and an input of 5 V unless otherwise specified. Only the specification with post irradiation limits are tested after radiation exposure. 4. All package outline dimensions are in inches. 5. Performed at a DLA approved facility. 6.
