-- High efficiency for power savings
-- Targets pagers, wireless phones, PDAs, LED drivers
Microsemi Corp. (Nasdaq:MSCC - News), a leading manufacturer of power management integrated circuits, has introduced a new high efficiency dc-dc boost converter featuring low-battery detect circuitry that allows portable systems to enter their power-savings mode to protect vital data.
Designated the LX1732(TM), the new high current PFM boost converter targets low voltage portable systems applications that include pagers, wireless phones, PDAs, handheld computers and LED drivers. System-level architecture of the LX1732 makes it simple to implement and well suited for the short design cycles typical in these portable applications.
Circuit operation can start from as little as 1.1V input and operate from 0.7V after start-up, allowing the LX1732 to supply power to critical system components even after battery capacity no longer supports normal operation. Output voltage ranges from 2.2V to 5V with load currents of up to 200 milliamps.
When a portable system's power is on, but not in active use, the LX1732 draws a maximum "quiescent" current of 200 microamps, dropping to only 0.1 microamp in shutdown mode, thus maximizing overall battery life. Overall efficiency of the LX1732 is 88%.
The LX1732 -- packaged in an 8-pin MSOP surface mount package -- is available for immediate sampling and delivery, priced at $1.06 in quantities of 1,000. Complete technical information on the LX1732 and other Microsemi power management products is available on the Microsemi Web site, www.Microsemi.com. Samples can be ordered through this site, or from Microsemi sales representatives and franchised distributors.
