LM2614 - 400mA Sub-Miniature Adjustable DC-DC Converter

Download the LM2614 datasheet PDF. This datasheet also covers the LM2 variant, as both devices belong to the same 400ma sub-miniature adjustable dc-dc converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The LM2614 DC-DC converter is optimized for powering RF power amplifiers (PAs) from a single Lithium-Ion cell.

It steps down an input voltage of 2.8V to 5.5V to an output of 1.0V to 3.6V at up to 400mA (300mA for B grade).

Key Features

  • protect the device and system during fault conditions. The LM2614 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 LM2614 can be dynamically controlled for output voltage changes from 1.0V to 3.6V in < 30µs. The device features external compensation to tailor the response to a wide range of operating conditions. Ke.

LM2614 400mA Sub-Miniature Adjustable DC-DC Converter Optimized for RF Power Amplifiers August 2002 LM2614 400mA Sub-Miniature Adjustable DC-DC Converter Optimized for RF Power Amplifiers General Description The LM2614 DC-DC converter is optimized for powering RF power amplifiers (PAs) from a single Lithium-Ion cell. It steps down an input voltage of 2.8V to 5.5V to an output of 1.0V to 3.6V at up to 400mA (300mA for B grade). Output voltage is set using an analog input to VCON in the application circuit. The device offers three modes for mobile phones and similar RF PA applications. Fixed-frequency PWM mode minimizes RF interference. A SYNC input allows synchronizing the switching frequency in a range of 500kHz to 1MHz.
