  • Product introduction

peculiarity

  • Space-saving 3× 3mm Law Firm-10&eMSOP-10 package
  • Wide input voltage range of 3V to 20V
  • Wide output voltage range from 1V to 18V
  • The LM27341 can deliver a maximum output current of 1.5A
  • The LM27342 provides a maximum output current of 2A
  • High switching frequency of 2 MHz
  • 1.00 MHz frequency synchronization
    150mΩ NMOS switch internal bootstrap supply
    Internal Reference Voltage Accuracy of 1%
    Peak current mode, PWM mode
    LM27341Q and LM27342Q are qualified through AEC-Q100 and are manufactured in an automotive grade manufacturing process
    The LM27341 and LM27342 monolithic regulators, high frequency, PWM step-down DC-DC 10-pin LLP converters and 10-pin eMSOP packages.
    They contain all the active functions, providing local DC-DC with fast transient response and precise adjustment transitions with minimal PCB area.
    The LM27341 and LM27342 are easy to use with minimal external component count.
    Capable of driving a load of 1.5A or 2A respectively with the inside of a 150mΩ NMOS tube, the switch is at the best power density results at the time.
    World-class control circuitry allows on-times as low as 65 nanoseconds, supporting very high frequency conversions.
    The switching frequency is internally set to 2 MHz and 1 synchronized to 2.35 MHz, resulting in minimal surface-mount inductors and capacitors.
    Including having an external shutdown is a low shutdown current of over 70 nA.
    The LM27341 and LM27342 utilize peak current-mode control and internal compensation for wide operating conditions and high regulation.

illustrate

The LM27341 and LM27342 monolithic regulators, high frequency, PWM step-down DC-DC 10-pin LLP converters and 10-pin eMSOP packages. They contain all the active functions, providing local DC-DC with fast transient response and precise adjustment transitions with minimal PCB area.

The LM27341 and LM27342 are easy to use with minimal external component count. Capable of driving a load of 1.5A or 2A respectively with the inside of a 150mΩ NMOS tube, the switch is at the best power density results at the time. World-class control circuitry allows on-times as low as 65 nanoseconds, supporting very high frequency conversions. The switching frequency is internally set to 2 MHz and 1 synchronized to 2.35 MHz, resulting in minimal surface-mount inductors and capacitors. Even at very high operating frequencies, efficiencies of up to 90% are easily achievable. Including having an external shutdown is a low shutdown current of over 70 nA. The LM27341 and LM27342 utilize peak current-mode control and internal compensation for wide operating conditions and high regulation. Other features include internal soft-start circuitry to reduce inrush current, pulse pass-through current limiting, thermal shutdown, and output overvoltage protection.
