Description
The AP9151A 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 1.0 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 -55

API9151A Point of Load (POL) switching regulators are more efficient than competitive POLs. (See Table 5.)
