PIN FUNCTIONS

Pin #

Name

Description

1

EN

Channel 1 and channel 2 enable. The EN pin is a digital input that turns the regulator on

and off. Float EN or pull EN low to turn the regulator on; pull EN high to turn it off.

2

IMON1

Channel 1 current monitoring. Connect a resistor between the IMON1 and GND pins to

set the current monitor gain.

3

GND

System ground.

4

VIN2

Channel 2 supply voltage. Channel 2

’s typical input voltage (VIN) is 5V. Use a ceramic

decoupling capacitor to decouple the VIN2 pin. Connect VIN2 using a wide PCB trace.

5

VOUT2

Channel 2 output terminal.

6

IMON2

Channel 2 current monitoring. Connect a resistor between the IMON2 and GND pins to

set the current monitor gain.

7

SS2

Channel 2 soft start. Connect a capacitor between the SS2 and GND pins to set channel

2’s soft-start time (tSS).

8

SS1

Channel 1 soft start. Connect a capacitor between the SS1 and GND pins to set channel

1’s tSS.

9

VOUT1

Channel 1 output terminal.

10

VIN1

Channel 1 supply voltage. Channel 2

’s typical input voltage (VIN) is 12V. Use a ceramic

decoupling capacitor to decouple the VIN1 pin. Connect VIN1 using a wide PCB trace.

Notes:

1) Exceeding these ratings may damage the device.

2) The maximum allowable power dissipation is a function of the

maximum junction temperature TJ (MAX), the junction-to-

ambient thermal resistance θ

JA, and the ambient temperature

TA. The maximum allowable continuous power dissipation at

any ambient temperature is calculated by PD (MAX) = (TJ

(MAX) - TA) / θJA. Exceeding the maximum allowable power

dissipation can produce an excessive die temperature, which

may cause the regulator to 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 the EV5098-D-00A, 2-layer PCB, 54mmx46mm.

5) The value

of θ

JA given in this table is only valid for comparison

with other packages and cannot be used for design purposes.

These values were calculated in accordance with JESD51-7,

and simulated on a specified JEDEC board. They do not

represent the performance obtained in an actual application.
