Functional Pin Description

Pin No.

Pin Name

Pin Function

WL-CSP-6B

1.415x0.885

(BSC)

WDFN-6L 2x2

VIN

Power input. The input voltage range is from 2.2V to 5.5V. A

minimum of 4.7

F (RT5713) and 10F (RT5714) ceramic

capacitor should be connected to this pin with the shortest path.

This pin is the connection between two build-in switches in the

chip, which should be connected to the external inductor. The

inductor should be connected to this pin with the shortest path.

7 (Exposed

Pad)

GND

Device ground pin. This pin should be connected to input and

output capacitors with the shortest path. The exposed pad must

be soldered to a large PCB and connected to GND for

maximum power dissipation.

Chip enable input pin. High level voltage enables the device

while low level voltage turns the device off. This pin must be

terminated.

VOUT

Output voltage feedback pin. This pin should be connected

close to the output capacitor terminal for better voltage

regulation. A minimum of use two 10

F/6.3V/X5R/0402 ceramic

capacitors should be connected to this pin with the shortest

path.

VSEL

Output voltage selection pin. This pin must be terminated.

When VSEL pin tie to GND, VOUT level is follow Output-1.

When VSEL pin tie to VIN, VOUT level is follow Output-2.
