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.
