Description
The AP9153CLY 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 0.6 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 compact metal cases, they operate over the full -55oC to 125oC temperature range. The
AP9153CY Point of Load (POL) switching regulators are more efficient than competitive POLs. (See Table 5.)

Notes:
1. 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. Tested per MIL-PRF-38534
