MAX1722/MAX1723/

MAX1724

1.5μA I , Step-Up DC-DC

Converters in TSOT and µDFN

General Description

Beneﬁts and Features

● Up to 90% Efficiency

The MAX1722/MAX1723/MAX1724 compact, high-efficiency,

step-up DC-DC converters are available in tiny, 5-pin

TSOT packages. They feature an extremely low 1.5μA

quiescent supply current to ensure the highest possible

light-load efficiency. Optimized for operation from one

to two alkaline or nickel-metal-hydride (NiMH) cells, or

a single Li+ cell, these devices are ideal for applications

where extremely low quiescent current and ultra-small

size are critical.

● No External Diode or FETs Needed

● 1.5μA Quiescent Supply Current

● 0.1μA Logic-Controlled Shutdown

● ±1% Output Voltage Accuracy

● Fixed Output Voltage (MAX1724) or Adjustable

Output Voltage (MAX1722/MAX1723)

● Up to 150mA Output Current

Built-in synchronous rectification significantly improves

efficiency and reduces size and cost by eliminating the

need for an external Schottky diode. All three devices

feature a 0.5Ω N-channel power switch. The MAX1722/

MAX1724 also feature proprietary noise-reduction circuitry,

which suppresses electromagnetic interference (EMI)

caused by the inductor in many step-up applications. The

family offers different combinations of fixed or adjustable

outputs, shutdown, and EMI reduction (see Selector

Guide).

● 0.8V to 5.5V Input Voltage Range

● 0.91V Guaranteed Startup (MAX1722/MAX1724)

● Internal EMI Suppression (MAX1722/MAX1724)

● TSOT Package (0.9mm typ Height)

● µDFN Package (2mm x 2mm x 0.75mm)

Ordering Information and Selector Guide appears at end of
