Product Details

The LT8692S is a quad channel step-down, current mode, monolithic buck switching regulator. All regulators are synchronized to a single oscillator with a fixed frequency of 2MHz. The “S” at the end of the part number refers to the second-generation Silent Switcher® technology which includes integrated bypass capacitor to deliver a high frequency and small solution size with excellent EMI performance. The integrated capacitors also make it easier to achieve the advertised EMI performance by reducing layout sensitivity. This performance makes the LT8692S ideal for noise sensitive applications and environments. The highly integrated four-channel solution saves space and simplifies the design of compact boards.

Burst Mode operation enables ultralow standby current consumption, forced continuous mode can be used to control frequency harmonics across the entire output load range or spread spectrum operation can further reduce EMI emissions.

The fast, clean, low overshoot switching edges enable high efficiency operation at high switching frequencies, leading to a small solution size with wide control loop bandwidth for fast transient response.

APPLICATIONS

  • Camera Modules
