MPM3690-50A/B – 16V, DUAL 25A OR SINGLE 50A POWER MODULE

PIN FUNCTIONS

Pin Number

Name

Description

A1–A5, B1–B5, C1–

VOUT1

GND

Power output 1. Power output pins for channel 1.

A6, A7, B6, B7, D1–

D4, D9–D12, E1–E4,

E10, E11, E12, F1,

F2, F3, F6, F7, F10,

F11, F12, G1, G3,

G7, G10, G12, H1–

H7, H9–H12, J1, J5,

J8, J12, K1, K5–K8,

K12, L1, L12, M1,

M12

Power ground. GND is the ground of the regulated output voltage (V_OUT).

A8–A12, B8–B12,

C9–C12

VOUT2

Power output 2. Power output pins for channel 2.

VS1P,

VS2P

Positive input of the remote-sense amplifier. Connect these pins to the

V_OUTremote sense point.

C5, C8

Negative input of the remote-sense amplifier. Connect these pins to the

output GND remote sense point to enable remote sense. Connect directly

to GND to disable the remote sense function.

VS1N,

VS2N

D6, C7

Frequency set. Connect a resistor between these pins and AGND to

configure the switching frequency (f_SW) between 400kHz to 1MHz. For the

MPM3690-50B, the FSET1 and FSET2 resistors must be the same.

FSET1,

FSET2

C6, E7

Feedback voltage. Connect a resistor to these pins between VS1N and

D5, D7

E5, D8

G5, G4

FB1, FB2 VS2N to configure V_OUT. This pin is connected to VS1P and VS2P with a

60.4kΩ resistor.

Soft-start time setting. Connect a ceramic capacitor to set the soft-start

SS1, SS2

time (t_SS).

Ramp selection pin. Float these pins to set the internal compensation

ramp to high; pull these pins pin low to set the internal compensation ramp

to low.

RAMP1,

RAMP2

E8, F8

VSOUT

MODE

Not connected (internally floated). Float these pins.

Operation mode set. Pull MODE up to VCC for forced continuous

conduction mode (FCCM).

Enable pins. Drive EN pin high to turn the output on, drive it low to turn the

output off. Do not float this pin.

F5, F9

G2, G11

EN1, EN2

SW1, SW2 Switching nodes. Float these pins.

Protection mode selection. Connect PMODE to GND for latch-off mode,

pull PMODE up to VCC for hiccup mode.

PMODE

PG1, PG2

VCC

Power good outputs. The output of the PG pins is an open drain. Pull the

PG pins high with a pull-up resistor.

G9, G8

Output of the internal power supply. Float this pin or connect it to an

external 3.3V power supply to improve efficiency.

NC1, NC2,

NC3, NC4

E6, J6, J7, E9

Not connected (internally floated). Float these pins.

M2–M11, L2–L11, J2,

J3, J4, J9, J10, J11,

K2, K3, K4, K9, K10,

K11

VIN

Supply voltage. Connect input voltage between these pins and GND pins.
