DC/DC IJMODULE POWER PRODUCTS Buck-Boost uModule Regulator Family Overview Buck-boost uModule regulators are the best choice in applications where the input voltage may be above, below or equal to the desired out- put voltage, such as battery-powered or multiple input applications. For boost (step-up) applications, these uModule regulators provide true short-circuit protection, shutdown and soft start.

DC/DC IJMODULE POWER PRODUCTS Synchronizable or Parallelable Buck & Buck-Boost uModule Regulators To help alleviate thermal issues associated with high power currents, most Linear Technology uModule step-down (buck) regulators are designed such that their outputs can be tied together (paralleled) to support a common output voltage. Paralleled power modules may even have different input voltages for increased flexibility in system level power design. Synchronizing the power module's internal oscillator is often desired for easy noise filtering in sensitive applications and/or to create...

DC/DC IJMODULE POWER PRODUCTS Buck uModule Regulators with Output Voltage Tracking & Margining Intended for powering digital ICs and systems where the supply rails must rise and fall in a specific manner, many members of the uModule regulator family support coincident or ratiometric tracking of the supply rails. Furthermore, the availability of a PGood signal enables supply rail sequencing. Output voltage margining is useful to confirm worst case system performance and/or optimize system operating efficiency Part Number Input Voltage Range (V) Output Voltage Range (V) Soft Start ^Without...

DC/DC IJMODULE POWER PRODUCTS Buck & Buck-Boost uModule Regulators with High Efficiency at Light Load In applications where the output load is often 15% or less of the maximum rated output current, a light load feature may be desired to increase efficiency. Linear Technology's buck uModule regulators support two different light load modes. Burst Mode® operation or discon- tinuous conduction mode (DCM) operation offers the best efficiency at light load, but output ripple will be slightly higher. Although not as efficient as Burst Mode/DCM operation, pulse-skiping operation delivers lower...
