The MCP16301 is a highly integrated, high-efficiency,
fixed frequency, step-down DC-DC converter in a
popular 6-pin SOT-23 package that operates from input
voltage sources up to 30V. Integrated features include
a high side switch, fixed frequency Peak Current Mode
Control, internal compensation, peak current limit and
overtemperature protection. Minimal external
components are necessary to develop a complete
step-down DC-DC converter power supply.
High converter efficiency is achieved by integrating the
current limited, low resistance, high-speed N-Channel
MOSFET and associated drive circuitry. High
switching frequency minimizes the size of external
filtering components resulting in a small solution size.
The MCP16301 can supply 600 mA of continuous
current while regulating the output voltage from 2.0V to
15V. An integrated, high-performance peak current
mode architecture keeps the output voltage tightly
regulated, even during input voltage steps and output

The EN input is used to turn the device on and off.
While turned off, only a few micro amps of current are
consumed from the input for power shedding and load
distribution applications.
Output voltage is set with an external resistor divider.
The MCP16301 is offered in a space saving SOT-23-6
surface mount package.
