DESCRIPTION
The MP6905 is a low-drop, diode-emulator IC
with external switch; MP6905 replaces Schottky
diodes in high-efficiency, flyback converters.
The chip regulates the forward drop of the
external switch (about 30mV) and switches it off
when the voltage becomes negative. MP6905
has a light-load sleep mode that reduces the
quiescent current to <300uA.
MP6905 is available in a compact SOIC-8
package.

Notes:
1) Exceeding these ratings may damage the device.
2) 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

(MAX)-

)/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.
3) The device is not guaranteed to function outside of its
operating conditions.
4) Measured on JESD51-7, 4-layer PCB.
