The I2C interface is operable when VDD and AVIN are present, regardless of the state of the EN pin.
If the device is disabled by pulling the EN to a logic low, the output capacitor can actively be discharged. Per
default, this feature is disabled. Programming the EN_DISC bit to a logic high will discharge the output capacitor
via a typ. 300
Ω path on the SENSE+ pin.
SOFT START
The device incorporates an internal soft start circuitry that controls the ramp up of the output voltage after
enabling the device. This circuitry eliminates inrush current to avoid excessive voltage drops of primary cells and
rechargeable batteries with high internal impedance.
During soft start, the output voltage is monotonically ramped up to the minimum programmable output voltage.
After reaching this threshold, the output voltage is further increased following the slope as programmed in the
ramp rate settings (see RAMP RATE CONTROLLING) until reaching the programmed output voltage. Once the
nominal voltage is reached, regular operation as described above will continue.
The device is able to start into a pre biased output capacitor as well.
PROGRAMMING THE OUTPUT
The TPS6236x devices offer four similar registers to program the output. Two dedicated hardware input pins,
VSEL0 and VSEL1, are implemented for choosing the active register. The logic state of VSEL0 and VSEL1
select the register whose settings are present at the output. The VSEL0 and VSEL1 pins must be terminated
unless the internal pull-down resistors are activated.
The registers have a certain initial default value (see Table 2) and can be readjusted via I2C during operation.
This allows a simple transition between several output options by triggering the dedicated input pins. At the same
time since the presets can be readjusted during operation, this offers highest flexibility.

Via the I2C interface and/or the four preset options, the following output parameters can be changed:
Output voltage from 0.77 V to 1.4 V (TPS62360/62) and 0.5V to 1.77V (TPS62361B) with 10 mV granularity
Mode of operation: Power Save Mode or forced PWM mode
The slope for transition between different output voltages (Ramp Rate) can be changed via I2C as well. The
slope applies for all presets globally. See RAMP RATE CONTROLLING for further details.
Since the output parameters can be changed by dedicated pins for selecting presets and by I2C, the following
use scenarios are feasible:
Control the device via dedicated pins only, after programming the presets, to choose and change within the
programmed settings
Program via I2C only. The dedicated input pins have fixed connections. Changes are conducted by changing
the preset values of the active register.
Dedicated input pins and I2C mixed operation. The non active presets might be changed. The dedicated input
pins are used for the transition to the new output condition. Changes within an active preset via I2C are
feasible as well.
