SGM6601 Low-Power DC-DC Boost Converter

2022-01-15
●GENERAL DESCRIPTION:
■The SGM6601 is a high-frequency boost converter. The input voltage accepts a range of 1.8V to 5.5V. It is specified for small to medium LCD bias supply and white LED backlight supplies. The switching frequency can reach up to 1MHz, which supports both ceramic output capacitors and tantalum output capacitors.
■The internal 400mA switch current limit provides a low output voltage ripple. For low-power applications, this device allows the use of a small form factor inductor. Atypical low quiescent current of 20μA together with an optimized control scheme allows the device to achieve very high efficiency over the whole load current.
■The adjustable output voltage can reach a maximum of 38V ideally with a dual cell NiMH/NiCd battery or a single cell Li-ion battery. And a standard 3.3V/5V to 12V power conversion can also be achieved.
■The SGM6601 is available in TDFN-2×2-6L and TSOT-23-5 packages. It operates over an ambient temperature range of -40°C to +85°C.
