LM3075 - Synchronous Current Mode Buck Controller

National Semiconductor (now Texas Instruments)

General Description

The LM3075 is a current mode control, synchronous buck controller IC.

Use of synchronous rectification and pulseskipping operation at light load achieves high efficiency over a wide load range.

Fixed frequency operation can be obtained by disabling the pulse-skipping mode.

Key Features

n n n n n Input voltage range of 4.5V-36V Current Mode Control Skip mode operation available Cycle by cycle current limit 1.24V ± 2% Reference.

LM3075 High Efficiency, Synchronous Current Mode Buck Controller September 2005 LM3075 High Efficiency, Synchronous Current Mode Buck Controller General Description The LM3075 is a current mode control, synchronous buck controller IC. Use of synchronous rectification and pulseskipping operation at light load achieves high efficiency over a wide load range. Fixed frequency operation can be obtained by disabling the pulse-skipping mode. Current mode control assures excellent line and load regulation and a wide loop bandwidth for fast response to load transients. www.DataSheet4U.com Current mode control can be achieved by either sensing across the high side NFET or a sense resistor. The switching frequency can be selected as either 200 kHz or 300 kHz from an internal clock.
