illustrate
The LM2734 regulator is a monolithic, high-frequency, PWM step-down DC/DC converter in a thin 6-pin SOT23 package. It offers all the positive features, providing local DC/DC fast transient response and precise adjustment conversion with minimal PCB area.
With minimal number of external components, design support via WEBENCH ® online ™ The LM2734 is easy to use. Capable of propelling state-of-the-art 0.5 micron BiCMOS technology with internal 300mΩnmos switches using the highest power density available in 1A loads. World-class control circuitry allows 13ns to go up to the low, allowing the entire abnormal 3V to 20V input voltage range from 0.8V down to the lowest output voltage high frequency. The switching frequency is internally set to 550kHz (LM2734Y) or 1.6MHz (LM2734X), allowing very small surface mount inductors and capacitors. Even at very high operating frequencies, efficiencies of up to 90% are easily achievable. External shutdown is included with ultra-low standby 30nA. The LM2734 adopts current mode control and internal compensation functions with wide operating conditions and high regulation performance. Other features include internal soft-start circuitry to reduce inrush current, pulse pass-through current limiting, thermal shutdown, and output overvoltage protection.
