PIN FUNCTIONS

Package

Pin #

Name

Description

1

/FAULT

Fault indicator. /FAULT is an open drain output. /FAULT is pulled low when the LED is

short, open, or when thermal shutdown is occurring.

2

EN/DIM

Enable/dimming control. Pull EN/DIM high to enable the MPM6010. Apply a 100Hz to

2kHz external clock to EN/DIM for PWM dimming.

3

FB

LED current feedback input.

4

VCC

Internal 4.9V LDO output. Internal circuits integrate an LDO output capacitor, so there

is no need to add an external capacitor to VCC.

5

AGND

Analog ground. AGND is the reference ground of the logic circuit. AGND is connected

to PGND internally. There is no need to add external connections to PGND.

6, 7, 8, 12

SW

Switch output. Connection is not needed for these SW pins, but a large copper plane

is recommended (especially on pin 6, 7, and 8) for better heat sinking.

9, 10, 11

OUT

Power output. Connect LED+ to OUT. An output capacitor is needed on OUT.

13

BST

Bootstrap. A bootstrap capacitor is integrated internally. External connections are not

required on BST.

14, 15

PGND

Power ground. PGND is the reference ground of the power device. PGND requires

extra care during PCB layout. For best results, connect PGND with copper pours and

vias.

16

IN

Supply voltage. IN supplies power for the internal MOSFET and regulator. The

MPM6010 operates from a +4V to +36V input rail. A low ESR and low-inductance

capacitor is required to decouple the input rail. Place the input capacitor very close to

IN and connect it with wide PCB traces and multiple vias.

17

NC

No connection. NC must be left floating.
