LM2735 / LM2735 -Q1 520kHz / 1.6MHz的â ????节省空间的升压型和SEPIC DC- DC稳压器 LM2735/LM2735-Q1 520kHz/1.6MHz â Space-Efficient Boost and SEPIC DC-DC Regulator
DESCRIPON
The LM2735 is an easy-to-use, space-efficient 2.1A low-side switch regulator ideal for Boost and SEPIC DC-DC regulation. It provides all the active functions to provide local DC/DC conversion with fast-transient response and accurate regulation in the smallest PCB area. Switching frequency is internally set to either 520kHz or 1.6MHz, allowing the use of extremely
small surface mount inductor and chip capacitors while providing efficiencies up to 90%.
