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

The MAX17250 DC-DC boost converter is a high-

efficiency, low quiescent current, synchronous boost

(step-up) converter with True Shutdown™, program-

mable 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 wafer-level

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