LM2734 Thin SOT 1-A Load Step-Down DC-DC Regulator Features 3 DescriptionThe LM2734 regulator is a monolithic, high- Thin SOT-6 Package frequency, PWM step-down DC-DC converterina6-• 3.0-Vto 20-V Input Voltage Range pin Thin SOT package. The device provides all the active functionsto provide local DC-DC conversion
with fast transient response and accurate regulation in the smallest possible PCB area. Witha minimumof external components and online
design support through WEBENCH, the LM2734 regulatoris easyto use. The abilityto drive 1-A loads with an internal 300-mΩ NMOS switch using state-of- the-art 0.5-µm BiCMOS technology resultsin the best
power density available. The world-class control circuitry allows for on-times as low as 13 ns, thus supporting exceptionally high-frequency conversion over the entire 3-Vto 20-V input operating range
down to the minimum output voltage of 0.8 V.
Switching frequency is internally set to 550 kHz (LM2734Y)or 1.6 MHz (LM2734X), allowing the use of extremely small surface-mount inductors and chip capacitors. Even though the operating frequencies
are very high, efficiencies upto 90% are easyto
2 Applications achieve. External shutdownis included, featuring an
ultra-low standby currentof30 nA.• Local Point-of-Load Regulation Core Powerin HDDs The LM2734 regulator uses current-mode control and
internal compensationto provide high-performance• Set-Top Boxes regulation overa wide rangeof operating conditions.• Battery-Powered Devices Additional features include internal soft-start circuitry• USB Powered Devices to reduce inrush current, pulse-by-pulse current limit,
thermal shutdown, and output overvoltage protection.• DSL Modems Notebook Computers
