LM2619 Datasheet (National Semiconductor) - 500mA Sub-Miniature Step-Down DC-DC Converter

LM2619, 500mA Sub-Miniature Step-Down DC-DC Converter

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.

The device offers three modes for mobile phones

LM2619 Features

* 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 de
