The device provides all the • 2.1-A Switch Current Over Full Temperature active functions to provide local DC-DC conversion Range with fast-transient response and accurate regulation in the smallest PCB area. Switching frequency is • Current-Mode Control internally set to either 520 kHz or 1.6 MHz, allowing • Logic High Enable Pin the use of extremely small surface mount inductor • Ultra-Low Standby Current of 80 nA in Shutdown and chip capacitors, while providing efficiencies of up to 90%. Current-mode control and internal • 170-m Ω NMOS Switch compensation provide ease-of-use, minimal • ±2% Feedback Voltage Accuracy component count, and high-performance regulation • Ease-of-Use, Small Total Solution Size over a wide range of operating conditions. External – Internal Soft Start shutdown features an ultra-low standby current of 80 nA, ideal for portable applications. Tiny SOT-23, – Internal Compensation WSON, and MSOP-PowerPAD packages provide – Two Switching Frequencies space savings. Additional features include internal – 520 kHz (LM2735-Y) soft start, circuitry to reduce inrush current, pulse-by- pulse current limit, and thermal shutdown. – 1.6 MHz (LM2735-X) – Uses Small Surface Mount Inductors and Chip Device Information(1) Capacitors PART NUMBER PACKAGE BODY SIZE (NOM) – Tiny SOT-23, WSON, and MSOP-PowerPAD WSON (6) 3.00 mm × 3.00 mm Packages LM2735 SOT-23 (5) 1.60 mm × 2.90 mm • LM2735-Q1 is AEC-Q100 Grade 1 Qualified and MSOP-PowerPAD (8) 3.00 mm × 3.00 mm is Manufactured on an Automotive Grade Flow WSON (6) 3.00 mm × 3.00 mm LM2735-Q1 SOT-23 (5) 1.60 mm × 2.90 mm 2 Applications (1) For all available packages, see the orderable addendum at • LCD Display Backlighting For Portable the end of the data sheet.
