7 / 24 page LT3844 7 3844fb FUNCTIONAL DIAGRAM PIN FUNCTIONS BOOST (Pin 16): The BOOST pin is the supply for the bootstrapped gate drive and is externally connected to a low ESR ceramic boost capacitor referenced to SW pin. The recommended value of the BOOST capacitor, CBOOST, is 50 times greater than the total input capacitance of the topside MOSFET. In most applications 0.1μF is adequate. The maximum voltage that this pin sees is VIN + VCC, ground referred. Exposed Pad (Pin 17): SGND. The exposed leadframe is internally connected to the SGND pin. Solder the exposed pad to the PCB ground for electrical contact and optimal thermal performance. – + – + VIN UVLO (<4V) BST UVLO 8V REGULATOR FEEDBACK REFERENCE – + 1.231V 3.8V REGULATOR INTERNAL SUPPLY RAIL 1 9 6 VIN VCC UVLO (<6V) SHDN DRIVE CONTROL NOL SWITCH LOGIC DRIVE CONTROL BURST_EN VC CSS SENSE– VFB 0.5V 2μA 50μA Burst Mode OPERATION R S Q OSCILLATOR SLOPE COMP GENERATOR BOOST TG SW VCC PGND SYNC fSET RSET SENSE+ SGND BOOSTED SWITCH DRIVER CURRENT SENSE COMPARATOR 12 7 8 13 14 10 11 5 3 100mV 4 2 16 15 VREF + 200mV SOFT-START BURST DISABLE DRIVER FAULT CONDITION: VIN UVLO VCC UVLO VSHDN UVLO CSS CLAMPED TO VFB + VBE VREF ~1V gm ERROR AMP – + M1 D2 D3 D1 L1 (OPTIONAL) RSENSE 3844 FD CC2 CC1 R1 RA RB VIN CIN R2 CBOOST VOUT COUT CVCC RC |
