Top and bottom power switches are included with all necessary circuitry to minimize the need for external components. The built-in current sense amplifier with monitor and control pins allows accurate input or output current regulation and limiting. Low ripple Burst Mode operation enables high efficiency down to very low output currents while keeping the output ripple below 10mVP-P. A SYNC pin allows synchronization to an external clock. Internal compensation with peak current mode topology allows the use of small inductors and results in fast transient response and good loop stability. The EN/UV pin has an accurate 1V threshold and can be used to program VIN undervoltage lockout or to shut down the LT8613 reduc- ing the input supply current to 1µA. A capacitor on the TR/SS pin programs the output voltage ramp rate during start-up. The PG flag signals when VOUT is within ±9% of theprogrammedoutputvoltageaswellasfaultconditions. The LT8613 is available in a small 28-lead 3mm × 6mm QFN package with exposed pad for low thermal resistance. 5V Step-Down Converter with 6A Output Current Limit Efficiency at 5VOUT applicaTions n Rail-to-Rail Current Sense Amplifier with Monitor n Wide Input Voltage Range: 3.4V to 42V n Ultralow Quiescent Current Burst Mode® Operation: 3μA IQ Regulating 12VIN to 3.3VOUT Output Ripple < 10mVP-P n High Efficiency Synchronous Operation: 95% Efficiency at 3A, 5VOUT from 12VIN 94% Efficiency at 3A, 3.3VOUT from 12VIN n Fast Minimum Switch-On Time: 40ns n Low Dropout Under All Conditions: 250mV at 3A n Allows Use Of Small Inductors n Low EMI n Adjustable and Synchronizable: 200kHz to 2.2MHz n Current Mode Operation n Accurate 1V Enable Pin Threshold n Internal Compensation n Output Soft-Start and Tracking n Small Thermally Enhanced 3mm × 6mm 28-Lead QFN Package n Automotive and Industrial Supplies n General Purpose Step-Down n CCCV Power Supplies L , LT, LTC, LTM, Burst Mode, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
