3W, 0.85V Startup
Voltage, Synchronous Step-Up Converter
Product Description
The GS5801 is a high efficiency synchronous step-up converter that can provide up to 3W of power to a boosted output from a low
voltage source. Unlike most step-up converter, not only it starts up at a very low input
voltage as low as 0.85V, it also incorporates circuits that disconnect the input from output, during shutdown, short-circuit, output current overloading, or other events when output is higher than the input. This eliminates the need for an external
MOSFET and its control circuitry to disconnect the input from output, and provides robust output overload protection.
The GS5801 starts up from a
voltage as low as 0.85V making it ideal for applications with single-cell or two-cell alkaline, NiCd, and NiMh batteries. A switching frequency of 2MHz minimizes solution footprint by allowing the use of tiny and low profile inductors and ceramic
capacitors. An internal synchronous
MOSFET provides high...
