General Description
The MCP16301/H devices are highly integrated,
high-efficiency, fixed-frequency, step-down DC-DC
converters in a popular 6-pin SOT-23 package, that
operate from input voltage sources up to 36V.
Integrated features include a high-side switch,
fixed-frequency peak current mode control, internal
compensation, peak current limit and overtemperature
protection. Only a few 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/H devices 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 current transient conditions that are
common in power systems.
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/H devices are offered in a
space-saving SOT-23-6 surface mount package.
