What are the key features of MCP1602-250I/MS?

20 MHz switching frequency enabling ultra-small external inductors and capacitors for miniature buck converter solutions
Automatic PFM/PWM switching maintains high efficiency from full 500 mA load down to light-load standby conditions
2.7 V to 5.5 V input range with fixed 2.5 V output in MSOP-8 for single-cell Li-Ion or 3.3 V rail step-down

What is MCP1602-250I/MS used for?

The MCP1602-250I/MS targets portable consumer electronics and IoT edge nodes where a single-cell Li-Ion battery must be regulated to 2.5 V at up to 500 mA with minimal standby power. Its 20 MHz switching frequency reduces the external inductor to sub-µH values, shrinking the total solution footprint to under 5 mm² for wearables and hearing aid modules. The automatic PFM/PWM mode ensures high efficiency across the full 0 mA to 500 mA load range, extending battery life in duty-cycle-heavy designs.

Frequently Asked Questions

What switching frequency does MCP1602-250I/MS use, and what size inductor does this enable?

The MCP1602-250I/MS operates at 20 MHz, allowing designers to use inductors as small as 470 nH and ceramic output capacitors below 1 µF, resulting in a total solution area under 5 mm² for ultra-compact portable power stages.

How does the PFM/PWM auto-switching in MCP1602-250I/MS improve battery life compared to a fixed-PWM regulator?

At light loads below about 10% of the 500 mA rated current, the device automatically transitions to PFM mode, reducing switching losses and quiescent current, which can extend battery runtime by 20% to 40% in systems that spend most of their time in standby.

Can MCP1602-250I/MS power a 2.5 V MCU directly from a Li-Ion cell that discharges from 4.2 V down to 2.7 V?

Yes. The device regulates its fixed 2.5 V output across the full 2.7 V to 5.5 V input range, so it maintains a stable 2.5 V rail from a fully charged 4.2 V cell all the way to the 2.7 V minimum input, covering the entire useful discharge curve of a standard Li-Ion battery.
