LM2735SD3.3EVAL

520KHZ/1.6MHZ - SPACE-EFFICIENT BOOST AN.

The LM2735SD3.3EVAL is a 520kHz or 1.6MHz space efficient boost and SEPIC DC to DC regulator LM2735X SEPIC 6Pin LLP evaluation board. This demo board converts 3V to 5.5V input to 3.3V output for up to 500mA load current. This is a two layer board using the bottom layer as a ground plane. It provides all the active functions to provide local DC to 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%. 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 shutdown features an ultra low standby current of 80nA ideal for portable applications.
