This product integrates an enhanced gate driver IC and Power Block Technology to complete the power stage switching function. This combination produces a high current, high efficiency, high speed switching device and delivers an excellent thermal solution in a small 5-mm × 6-mm outline package due to its large ground based thermal pad. In addition, the PCB footprint has been optimized to help reduce design time and simplify the completion of the overall system design. spacer spacer spacer V 100 6 IN 90 5 C IN V = 5V GS V CSD97370Q5M 80 4 DD V = 12V IN V = 1.2V L OUT O V OUT V L = 0.3μH 70 OUT 3 V CC OUT f = 500kHz V SW PWM1 OUT T = 25ºC A C OUT 60 2 SS PWM2 RT P 50 1 GND 40 0 L 0 5 10 15 20 25 O Multi Phase Output Current (A) Control IC CSD97370Q5M S0488-03 Figure 1.
