Applications
The MCP16363T-E/NMX is designed for industrial equipment powered from 24V or 48V bus rails, including PLCs, motor drives, and factory automation controllers requiring a regulated lower-voltage supply. Its 2 MHz switching frequency with PWM dither makes it attractive for noise-sensitive RF and communication hardware. It is also used in automotive infotainment and ADAS power trees where the 48V mild-hybrid bus must be stepped down efficiently to 3.3V or 5V logic rails.

Frequently Asked Questions
How does the MCP16363T-E/NMX handle EMI compliance in a 48V industrial power supply?
The device switches at up to 2 MHz and uses PWM dither to spread spectral energy, reducing peak EMI emissions by several dB and helping designs meet CISPR 32 or IEC 61000 limits with smaller filter components on a 48V input rail.
What efficiency advantage does PFM mode provide in battery-powered 24V systems using the MCP16363T-E/NMX?
At light loads below roughly 10% of rated current, the MCP16363T-E/NMX automatically transitions from PWM to PFM control, cutting switching losses and maintaining efficiency above 80% even at standby currents in the low-milliamp range on a 24V rail.
For a compact automotive 48V-to-5V converter, how much board area does the MCP16363T-E/NMX VDFN-8 package require?
The VDFN-8 package measures approximately 3 mm x 3 mm, and the 2 MHz switching frequency allows use of inductors as small as 1 µH, so the complete converter footprint can fit within 10 mm x 10 mm on an automotive PCB with 48V input.
When is the MCP16363T-E/NMX a better choice than a 36V-rated buck converter for telecom shelf power?
Telecom rectifiers can present bus transients exceeding 36V, so the MCP16363T-E/NMX with its 48V absolute maximum input rating provides the headroom to survive those spikes without external clamping, reducing BOM count and improving MTBF in -48V telecom shelf designs.
