Description

The LM2735-Q1 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 provide local DC-DC conversion with fast-transient response and accurate regulation in the smallest PCB area. Switching frequency is internally set to either 520 kHz or 1.6 MHz, allowing the use of extremely small surface mount inductor and chip capacitors, while providing efficiencies of up to 90%. The device can be used as a post-boost, boosting from the main automotive system 3.3V rail to power CAN transceivers and other circuits requiring 5V. The 24V output capability allows the LM2735-Q1 to power audio amplifiers, antenna, power-over-coax (PoC), and automotive audio bus (A2B) devices as well. 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 80 nA, ideal for portable applications. Tiny SOT-23 and WSON packages provide space savings. Additional features include internal soft start, circuitry to reduce inrush current, pulse-by-pulse current limit, and thermal shutdown.
