Overview
MAX1722/MAX1723/ 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 ...
