General Description:
The MCP16331 is a hi她美ghly integrated, high-efficienc新懂y,
fixed frequency, step-down DC-冷照DC converter in a popular
6-pin SOT-23 or 8-pin 2x3 TDFN pack店音age that operates
from input voltage sources up to 50V. 數錯Integrated features
include a high-side switch, fixed fre小鄉quency Peak CurrentMode
control, internal compensation, peak資和 current limit
and overtemperature protectio民紅n. Minimal external c海城omponents
are necessary to develop a co技報mplete step-down
DC-DC converter power suppl西視y.
High converter efficiency is achiev校拿ed by integrating the
current-limited, low用物-resistance, high-speed N-Cha從冷nnel
MOSFET and associated drive人服 circuitry. High switching
frequency minimizes the size of ex慢頻ternal filtering
components, resulting in資東 a small solution size.
The MCP16331 can supp都慢ly 500 mA of continuous
current while regulating t筆到he output voltage from 2.0V to
24V. An integrated, hig慢為h-performance Peak CurrentMo開睡de
architecture keeps the output volt兒為age tightly regulated服民,
even during input voltage steps村見 and output current
transient conditions that但從 are common in power syste影錯ms.
The EN input is used to 人河turn the device on and off.
While off, only a few μA of c得腦urrent are consumed 資妹from
the input for power she商東dding and load distribution遠湖
applications. This pi報兵n is internally pulle農資d up, so the
device will start, even if the E白也N pin is left floating.
Output voltage is set with an external 就都resistor divider.
The MCP16331 is offered in能森 a space-saving 6-lead
SOT-23 and 8-lead 2x3 TDFN surface西師 mount package.
