Description

converter delivering high efficiency in a SOT23-6 package. The device has an internal NMOS switch and PMOS synchronous rectifier and has the capacity of supplying 3.3V at 100mA from a single AA cell input.

High frequency switching (up to 2MHz) minimizes the board area by allowing the use of tiny, low profile inductors and ceramic capacitors.

The KB3436 provides automatic pulse skipping at light loads, thus reducing the supply current for extended battery life. At shutdown, the KB3436 fully discharges the output to ground and draws no supply current.

The KB3436 is available in small SOT23-6 package with both fixed and adjustable output voltage versions.
