MHP8565A Datasheet | Microchip Technology

Single 3 Amp Point-of-Load Switching Regulator Product Overview Description The MHP series are non-isolated point-of-load switching regulators for high reliability military and space distributed power applications (MIL-PRF-38534 certified facility). Fully integrated, these include a buck controller, inductor, and input/output capacitors bined in a single package. They operate from an input voltage of +4.5V to +12V, providing step down power conversion to output voltages as low as 0.5V or lower. Operating Features include output voltage adjust, output current limit, and output enable/disable. Careful design and layout ensure excellent stability, transient response, and low noise operation. Packaged in a pact metal case, it operates over the full -55 °C to +125 °C temperature range. Features - Now available as SMD: 5962R1323601xxx - Single 3 amp product - Efficiencies to 87%, see Figure 6-7 - Radiation hard to 100K rad TID - Single-event results show no significant output transients through an LET of 58 Me V/(mg/cm2). - Optimized for 5V input. Consult factory for higher input voltages. - Operates down to 4.5 volts input - Current mode control - Adjustable output voltage between 0.5V and 4V (depends on model, see Table 3-1) - Enable function available - Operates at a nominal frequency of 500 KHz Applications/Benefits - More efficient than petitive POLs (See Figure 6-6). - FPGA power supply - satellite - ASIC power supply - satellite Figure 1.
