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

LM2619 Description

LM2619 500mA Sub-Miniature Step-Down DC-DC Converter October 2003 LM2619 500mA Sub-Miniature Step-Down DC-DC Converter General .
The LM2619 step down DC-DC converter is optimized for powering circuits from a single Lithium-Ion cell.

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

LM2619 Applications

* Fixed-frequency PWM mode minimizes RF interference. A SYNC input allows synchronizing the switching frequency in a range of 500kHz to 1MHz. Low current hysteretic PFM mode reduces quiescent current to 160µA (typ. ). Shutdown mode turns the device off and reduces battery consumption to 0.02µA (typ. ).
