DESCRIPTION
The MP6901 is a Low-Drop Diode Emulator IC
that, combined with an external switch replaces
Schottky diodes in high-efficiency, Flyback
converters. The chip regulates the forward drop
of an external switch to about 70mV and
switches it off as soon as the voltage becomes
negative. Package choices are a space saving
TSOT23-5 or SOIC-8.

Notes:
2) Exceeding these ratings may damage the device.
3) The maximum allowable power dissipation is a function of the
maximum junction temperature T
J
(MAX), the junction-to-
ambient thermal resistance θ
JA
, and the ambient temperature
T
A
. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by P
D
(MAX)=(T
J
(MAX)-
T
A
)/θ
JA
. Exceeding the maximum allowable power dissipation
will cause excessive die temperature, and the regulator will go
into thermal shutdown. Internal thermal shutdown circuitry
protects the device from permanent damage.
4) The device is not guaranteed to function outside of its
operating conditions.
5) Measured on JESD51-7, 4-layer PCB.
