LM2735YQMF/NOPB

TEXAS INSTRUMENTS  LM2735YQMF/NOPB  直流-直流开关升压, SEPIC稳压器, 可调, 2.7V-5.5V输入, 3V-24V输出, 2.1A输出, SOT-23-5

The is an easy-to-use space-efficient low-side Switch Regulator ideal for boost and SEPIC DC-to-DC regulation. The device 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 520kHz, allowing the use of extremely small surface mount inductor and chip capacitors, while providing efficiencies of 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. Additional features include internal soft-start, circuitry to reduce inrush current, pulse-by-pulse current limit and thermal shutdown.
