What are the key features of MCP16301T-I/CHY?
- Wide 4V to 30V input voltage range with integrated switch in a 6-pin SOT-23 package enabling compact step-down regulator designs from 12V or 24V industrial rails
- Current-mode PWM control with fast transient response and cycle-by-cycle current limiting for reliable short-circuit protection in demanding power supply designs
- Adjustable output voltage with minimal external components reduces BOM count and PCB area compared to traditional buck converters requiring external FETs
What is MCP16301T-I/CHY used for?
MCP16301T-I/CHY is used in industrial power supplies, automotive accessory regulators, and embedded system power trees where a 4V to 30V input must be stepped down to a lower regulated voltage in a small footprint. Its 6-pin SOT-23 package suits space-constrained designs such as IoT gateway power modules, 12V automotive USB chargers, and sensor node power conditioners where a compact, efficient PWM buck regulator reduces external component count.

Frequently Asked Questions
What input voltage range does MCP16301T-I/CHY support and how does this suit 12V and 24V industrial power rails?
MCP16301T-I/CHY accepts an input voltage of 4V to 30V, with a 12V nominal input rating, making it directly compatible with standard 12V automotive and industrial power rails as well as 24V industrial bus supplies. A single MCP16301T-I/CHY can replace a larger discrete buck converter in panel instruments, industrial sensors, and 24V PLC I/O modules requiring a compact, high-voltage-capable step-down solution.
How does current-mode PWM control in MCP16301T-I/CHY benefit designs with rapidly changing load currents?
Current-mode PWM control in MCP16301T-I/CHY provides inherent cycle-by-cycle current limiting and faster load transient response compared to voltage-mode control, because the inner current loop reduces output voltage deviation when the load suddenly changes. This is advantageous in microcontroller supply rails, RF transmit bursts, and motor pre-driver supplies where load steps of tens to hundreds of milliamps occur within microseconds.
Why is the 6-pin SOT-23 package of MCP16301T-I/CHY well-suited for space-constrained IoT sensor nodes?
The SOT-23-6 package of MCP16301T-I/CHY occupies a PCB footprint of approximately 2.9mm × 1.6mm, which is significantly smaller than an 8-pin SOIC or SO-8 alternative while supporting the same 30V input capability. For a battery-backed IoT sensor node powered from a 12V solar panel or lithium-thionyl primary cell through a 4V to 30V input range, this compact footprint allows the power supply to fit within 50mm² of total PCB area alongside the MCU and radio.
