Pin Name

Description

1

VIN

Main Power Input Pin. Connect this pin to a voltage source and an input

capacitor. The TD5860/TD5860A sources current to VOUT pin by controlling the

upper pass MOSFET, providing a current path from VIN to VOUT.

2

GND

Power and Signal Ground. Connect this pin to system ground plane with shortest

traces. The TD5860/TD5860A sinks current from VOUT pin by controlling the

lower pass MOSFET, providing a current path from VOUT to GND. This pin is

also the ground path for internal control circuitry.

3

VREF

Reference Voltage Input and Active-high Enable Control Pin. Apply a voltage to

this pin as a reference voltage for the TD5860/TD5860A. Connect this pin to a

resistor diver, between VIN and GND, and a capacitor for filtering noise purpose.

Applying and holding the voltage below the enable voltage threshold on this pin

by an open-drain transistor shuts down the output. During shutdown, the VOUT

pin has high input impedance.

4

VOUT

I Output Pin of The Regulator. Connect this pin to load and output capacitors

(>8

μF MLCC is necessary) required for stability and improving transient

response. The output voltage is regulated to track the reference voltage and

capable of sourcing or sinking current up to 1.5A/2A.

5,7,8

NC

No Internal Connection.

6

VCNTL

Power Input Pin for Internal Control Circuitry. Connect this pin to a voltage

source, providing a bias for the internal control circuitry. A decoupling capacitor is

connected near this pin.

Exposed Pin

GND

Chip Substrate Connection of The Chip. Connect this pad to system ground plane

for good thermal conductivity.
