It offers a high efficiency, low component count, compact solution for a wide input voltage: 3.9V to 23V The 4 internal low resistance NMOS switches minimize the size of the application circuit and reduce power losses to maximize efficiency. Internal high side gate drivers, which require only the addition of two small external capacitors, further simpli...
