Step-down controller

  • 06-May-2009 04:48 EDT

Linear Technology’s LTC3824H is a 4- to 60-V input range, low-quiescent current step-down dc/dc controller. Packaged in a small thermally enhanced MSOP-10, the H-grade device is guaranteed up to a 150°C (302°F) operating junction temperature range. The LTC3824 is suitable for automotive applications subjected to high ambient temperatures, demanding a small solution size for output voltages ranging from 0.8 V to VIN at up to 5 amps. The device’s 4-V minimum input voltage supports automotive cold crank, and the 60-V maximum input voltage survives inductive load dumps without the need for external clamping circuits. The LTC3824H can be configured for burst-mode operation, which reduces the controller’s no-load current draw to only 40 uA and safely powers prebiased loads. The shutdown current is 7 uA. With 100% duty cycle capability, the LTC3824H has a very low dropout voltage.
