DescriptionThe LM2735YMF/NOPB device is an easy-to-use, space-efficient 2.1-A low-side switch regulator,ideal for Boost and SEPIC DC/DC regulation. The device provides all the active functions to providelocal DC-DC conversion with fast-transient response and accurate regulation in the smallest PCBarea. Switching frequency is internally set to either 520 kHz or 1.6 MHz, allowing the use ofextremely small surface mount inductor and chip capacitors, while providing efficiencies of up to90%. Current-mode control and internal compensation provide ease-of-use, minimal component count,and high-performance regulation over a wide range of operating conditions. External shutdownfeatures an ultra-low standby current of 80 nA, ideal for portable applications. Tiny SOT-23, WSON,and MSOP-PowerPAD packages provide space savings. Additional features include internal soft start,circuitry to reduce inrush current, pulse-by-pulse current limit, and thermal shutdown.
