Description	500mA Sub-Miniature Step-Down DC-DC Converter
Datasheet	LM2619 Datasheet

The LM2619 step down DC-DC converter is optimized for powering circuits from a single Lithium-Ion cell.

It steps down an input voltage of 2.8V to 5.5V to an output of 1.5V to 3.6V at up to 500mA.

Output voltage is set using resistor feedback dividers.

protect the device and system during fault conditions. The LM2619 is available in a 10 bump micro SMD package. This packaging uses National’s chip-scale micro SMD technology and offers the smallest possible size. A high switching frequency (600kHz) allows use of tiny surface-mount components. The device features external compensation to tailor the response to a wide range of operating conditions.
