Microchip Expands Space Power Portfolio with New Radiation-Tolerant GaN Point-of-Load Converter

MCHP
  • Microchip Technology announced the POL-05-20S-T, a radiation-tolerant Point-of-Load converter designed for space processing applications.
  • The device utilizes Gallium Nitride (GaN) technology to deliver up to 20A of output current with high efficiency & power density.
  • It is housed in a compact 25g surface-mount package measuring 1.51" x 1.51" x 0.45".
  • The converter supports fast-transient applications for core voltage rails of FPGAs, microcontrollers, ASICs, & other digital loads using synchronous buck topology.
  • Electrical specifications include a wide input range of 4.75V to 13.2V & an adjustable output voltage from 0.7V to 5V.
  • The unit is characterized for radiation environments with Total Ionizing Dose (TID) up to 50 krad & Single Event Effects (SEE) up to 43 MeV·cm²/mg.
  • Operating temperature range extends from −55°C to +100°C at full load.
  • Protection features include remote sensing, undervoltage & overvoltage protection, soft start, an enable pin, & power-good indication.
  • The POL-05-20S-T is available in production quantities for direct purchase or through authorized distributors.
  • This product expands Microchip's comprehensive space power suite which includes EMI filters, DC-DC converters, & high-performance computing devices.
