DESCRIPTION

NAME

NO.

Input to adjust output voltage of converter 2. In adjustable version (TPS62410) connect an external

ADJ2

1

I

EasyScale™ interface is used for converter 2, this pin must be directly connected to the output.

This Pin has 2 functions:

1.

Operation mode selection: With low level, power-save mode is enabled where the device operates

in PFM mode at light loads and enters automatically PWM mode at heavy loads. Pulling this PIN

to High forces the device to operate in PWM mode over the whole load range.

MODE/DATA

I

2.

EasyScale™ interface function: One wire serial interface to change the output voltage of both

converters. The pin has an open-drain output to provide an acknowledge condition if requested.

The current into the open-drain output stage may not exceed 500

μA. The interface is active if

either EN1 or EN2 is High.

capacitor is connected between this pin and the error amplifier. In case of fixed output voltage versions

or when the Interface is used, this pin is connected to an internal resistor divider network.

This pin defines the output voltage of converter 1. The pin acts in TPS62410 as an analog input for

output voltage setting through external resistors. In fixed default output voltage versions this pin is a

digital input to select between two fixed default output voltages.

In TPS62410 an external resistor network needs to be connected to this pin to adjust the default output

voltage.
