MAX17250

2.7V to 18V Input, Boost Converter with 0.1μA

True Shutdown, Short-Circuit Protection

and Selectable Input Current Limit

General Description

Beneﬁts and Features

● Input Voltage Range 2.7V to 18V

TheMAX17250DC-DCboostconverterisahigh-efficiency,

low quiescent current, synchronous boost (step-up)

converter with True Shutdown™, programmable input

current limit, and short-circuit protection. The MAX17250

has a wide input voltage range of 2.7V to 18V and

generates an output voltage of 3V to 18V. The MAX17250

has a maximum on-time of 800ns and implements three

modes of operation. The first mode of operation is a

soft-start mode at power-up. The second mode of

operation is normal operation and utilizes a fixed on-time/

minimum off-time Pulse Frequency Modulation (PFM)

architecture that uses only 60μA (typ) quiescent

current due to the converter switching only when needed.

The last mode is True Shutdown, where the output is

completely disconnected from the input, and the battery

drain is minimized to 0.1μA (typ) shutdown current. The

MAX17250 is available in a compact, 12-bump, 1.72mm

x 1.49mm WLP or a 14-pin, 3mm x 3mm TDFN package.
