BL8536
DESCRIPTION
FEATURES
The BL8536 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 0.9V, and only consumes 15u A at standby, making it an ideal choice for single cell alkaline/Ni MH battery operations.
A switching frequency of 1MHz minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. The current mode PWM design is internally pensated, reducing external parts count.
BL8536 is available in SOT23-3、SOT23-5 and SOT89-3 Packages.
