illustrate

The LM2735 is an easy-to-use, space-saving 2.1A low-side switch boost and ideal for SEPIC DC-DC regulators. It offers all the positive features, providing fast transient response and minimal PCB area to precisely regulate local DC/DC conversion. The switching frequency is set internally at 520kHz or 1.6MHz, allowing the use of very small surface mount inductors and chip capacitors while providing efficiencies of up to 90%. Current pattern control and internal compensation provide ease of use, minimal component count, and high performance operating conditions for extensive regulation. Ideal for portable applications with 80 nA with external shut-off function Ultra-low standby current. The miniature SOT23-5, LLP-6, and eMSOP-8 packages provide space savings. Other features include internal soft-start, circuitry to reduce inrush current, pulse through pulse current limiting and thermal shutdown.
