MAX1724
1.5μA IQ, Step-Up DC-DC
Converters in TSOT and µDFN
General Description
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.
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).

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
Electrical Characteristics
(VBATT = 1.2V, VOUT = 3.3V (MAX1722/MAX1723), VOUT = VOUT(NOM) (MAX1724), SHDN = OUT, RL = ∞, TA = 0°C to +85°C,
unless otherwise noted. Typical values are at TA = +25°C.) (Note 1)
