Manufacturer Part Number
sip12202db
Description
5.5-v, 500-khz Synchronous Buck Controller Demo Board
Manufacturer
Vishay
Datasheet
DESCRIPTION
This demo board allows users to see how SiP12202 works
as a central control unit in a high efficiency, high current
DC-to-DC buck converter. It accepts an input voltage of
2.7 V - 5.5 V and outputs 2.5 V.
This board incorporates the SiP12202 buck controller IC, the
high-side P-Ch MOSFET Si7106DN and low-side N-Ch
MOSFET Si7601DN, the place for an optional 3 A schottky
diode, the output L-C filter, input power supply with
decoupling
components
This board can be used as an evaluation vehicle for this
SiP12202 buck controller IC.
