1 / 58 page  LM2735 www.ti.com SNVS485F – JUNE 2007 – REVISED APRIL 2013 LM2735/LM2735-Q1 520kHz/1.6MHz – Space-Efficient Boost and SEPIC DC-DC Regulator Check for Samples: LM2735 1 FEATURES DESCRIPTION The LM2735 is an easy-to-use, space-efficient 2.1A 2 • Input Voltage Range 2.7V to 5.5V low-side switch regulator ideal for Boost and SEPIC • Output Voltage Range 3V to 24V DC-DC regulation. It provides all the active functions • 2.1A Switch Current over Full Temperature to provide local DC/DC conversion with fast-transient Range response and accurate regulation in the smallest PCB area. Switching frequency is internally set to either • Current-Mode Control 520kHz or 1.6MHz, allowing the use of extremely • Logic High Enable Pin small surface mount inductor and chip capacitors • Ultra Low Standby Current of 80 nA in while providing efficiencies up to 90%. Current-mode Shutdown control and internal compensation provide ease-of- use, minimal component count, and high- • 170 m Ω NMOS Switch performance regulation over a wide range of • ±2% Feedback Voltage Accuracy operating conditions. External shutdown features an • Ease-of-Use, Small Total Solution Size ultra-low standby current of 80 nA ideal for portable applications. Tiny SOT-23, WSON, and MSOP- – Internal Soft-Start PowerPAD packages provide space-savings. – Internal Compensation Additional features include internal soft-start, circuitry – Two Switching Frequencies to reduce inrush current, pulse-by-pulse current limit, and thermal shutdown. – 520 kHz (LM2735-Y) – 1.6 MHz (LM2735-X) – Uses Small Surface Mount Inductors and Chip Capacitors – Tiny SOT-23, WSON, and MSOP-PowerPAD Packages • LM2735-Q1 is AEC-Q100 Grade 1 Qualified and is Manufactured on an Automotive Grade Flow APPLICATIONS • LCD Display Backlighting For Portable Applications • OLED Panel Power Supply • USB Powered Devices • Digital Still and Video Cameras • White LED Current Source • Automotive 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
