LMR12010XMKE

TEXAS INSTRUMENTS  LMR12010XMKE  直流-直流开关降压逐步递减稳压器, 可调, 3V-20V输入, 800mV-17V输出, 1A输出, SOT-23-6

The is a SIMPLE SWITCHER® monolithic high-frequency PWM step-down DC-to-DC Converter provides all the active functions to provide local DC-to-DC conversion with fast transient response and accurate regulation in the smallest possible PCB area. With a minimum of external components and online design support through WEBENCH®, the LMR12010 is easy to use. The ability to drive 1A loads with an internal 300mR NMOS switch using state-of-the-art 0.5µm BiCMOS technology results in the best power density available. The world class control circuitry allows for on-times as low as 13ns, thus supporting exceptionally high frequency conversion over the entire 3 to 20V input operating range down to the minimum output voltage of 0.8V. Switching frequency is internally set to 1.6MHz, allowing the use of extremely small surface mount inductors and chip capacitors. Even though the operating frequencies are very high, efficiencies up to 90% are easy to achieve.
