BMR46 series PoL Regulators
BMR46 series PoL Regulators
Input 4.5-14 V, Output up to 50 A / 165 W
Input 4.5-14 V, Output up to 50 A / 165 W
Unused input pins
Unused SDA, SCL and GCB pins should still have pull-up
resistors as specified.
Unused VTRK or SYNC pins should be left open or connected
to the PREF pin.
Unused CTRL pin can be left open due to internal pull-up.
VSET and SA0/SA1 pins must be used. These pins must have
pin-strap resistors or strapping settings as specified.
PWB layout considerations
The pin-strap resistors, R
SET
as close to the product as possible to minimize loops that may
pick up noise.
Avoid current carrying planes under the pin-strap resistors and
the PMBus signals.
The capacitor C
(or capacitors implementing it) should be
I
placed as close to the input pins as possible.
Capacitor C
(or capacitors implementing it) should be placed
O
close to the load.
Care should be taken in the routing of the connections from
the sensed output voltage to the S+ and S– terminals. These
sensing connections should be routed as a differential pair,
preferably between ground planes which are not carrying high
currents. The routing should avoid areas of high electric or
magnetic fields.
