BL8542B Overview
The BL8542B is a step-up converter that provides a boosted output voltage from a low voltage source. Because of its proprietary design, it starts up at a very low input voltage down to 850mV, making it an ideal choice for single cell alkaline/NiMH battery operations. A switching frequency of 1MHz minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors.
BL8542B Key Features
- Up to 95% Efficiency -- Output voltage accuracy 3％ -- 1MHz Switching Frequency allows small inductor
BL8542B Applications
- One to Three Cell Battery Operated Devices -- Medical Instruments -- Bluetooth Headsets -- Flash-Based MP3 Players -- Noise Canceling Headphones
