DESCRIPTION
The MHP 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 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 -55°C to
+125°C temperature range.
