SGM6601 Low-Power DC-DC Step-Up Converter

GENERAL DESCRIPTION

The SGM6601 is a high-frequency boost converter dedicated for small to medium LCD bias supply and white LED backlight supplies. The device is ideal to generate output voltages up to 38V from a dual cell NiMH/NiCd or a single cell Li-ion battery. The part can also be used to generate standard 3.3V/5V to 12V power conversions.

The SGM6601 operates with a switching frequency up to 1MHz. This allows the use of small external components using ceramic as well as tantalum output capacitors. Together with the small package, the SGM6601gives a very small overall solution size. The SGM6601 has an internal 400mA switch current limit, offering low output voltage ripple and allows the use of a small form factor inductor for low power applications. The low quiescent current (20μA TYP) together with an optimized control scheme, allows device operation at very high efficiencies over the entire load current range.

The SGM6601 is available in the Green TDFN-2×2-6L and TSOT-23-5 packages. It operates over an ambient temperature range of -40 to +85.
