23V Buck-Boost Converter with Integrated MOSFETs

REG 0x0E: Converter Control 1 (R/W) (NVM)

Bit

Description

Comment

0: Disable

1: Enable

If this bit is low, the converter is always disabled. If

this pin is High, then either the EN pin or the

EN_OVERRIDE bit will enable the converter. In

addition, the HIZ mode bit (Reg 0x00, bit 7) must be

low.

EN_OVERRIDE

0: Disable

1: Enable

If this bit is high, EN pin is over written and the

converter is enabled by the EN bit. This allows user

to enable the converter from I2C without using the

EN pin.

0: 1.5ms

1: 5ms

Soft start time for the output voltage:

RFU

Reserved for future use. Do not change.

OFF_DLY[1]

00: Disable

01: 10s

10: 20s

11: 30s

When light load is detected for the setting time, the

output is disabled and latched off. The IC must be

put into the HIZ state (disabled) and back into the

POWER ON state (enabled) to turn the converter

back on. This can be done with the EN Pin, or

through the EN Register

OFF_DLY[0]

EN_POLARITY

0: Active Low

1: Active High

Controls the polarity of the EN input pin.

OFF_LOAD_EN

0: Disable

1: Enable

When light load is detected for longer than the

OFF_DLY time, the converter is disabled and latched

off. The converter must be disabled and re-enabled

to turn back on. This can be done with the EN pin or

the EN register bit.
