Features • 30V DMOS FET switch • 1.6 MHz switching frequency • Low RDS(ON) DMOS FET • Switch current up to 800 mA • Wide input voltage range (2.7V–14V) • Low shutdown current (<1 µA) • 5-Lead SOT-23 package • Uses tiny capacitors and inductors • Cycle-by-cycle current limiting • Internally compensated Description The LM27313 switching regulator is a current-mode boost converter with a fixed operating frequency of 1.6 MHz. The use of the SOT-23 package, made possible by the minimal losses of the 800 mA switch, and small inductors and capacitors result in extremely high power density. The 30V internal switch makes these solutions perfect for boosting to voltages of 5V to 28V. This part has a logic-level shutdown pin that can be used to reduce quiescent current and extend battery life. Protection is provided through cycle-by-cycle current limiting and thermal shutdown. Internal compensation simplifies design and reduces component count. Applications • White LED Current Source • PDA’s and Palm-Top Computers • Digital Cameras • Portable Phones, Games and Media Players • GPS Devices

Reliability Metrics

Part Number	Process	EFR Reject	EFR Sample Size	PPM	LTA Rejects	LTA Device Hours	FITS	MTTF (Hours)
LM27313XMF	ABCD150	0	34175	0	0	4234000	1	1201409060

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
