36、R, COLUMBUS COLUMBUS, OHIO SIZE A CODE IDENT NO. 16236 DWG NO. V62/08610 REV A PAGE 10 Terminal symbol Terminal Description CPVOUT This pin represents the output of the charge pump. The voltage at this pin is the bias voltage for the integrated circuit. Connect a decoupling capacitor from this pin t

37、o ground. The value of the decoupling capacitor should be at least 10x the value of the charge pump capacitor. This pin may be tied to the bootstrap circuit as the source for creating the BOOT voltage. CT1, CT2 These pins are the connections for the external charge pump capacitor. A minimum of a 0.1

38、 F ceramic capacitor is recommended for proper operation of the integrated circuit. OCSET Connect a resistor (ROCSET) from this pin to the drain of the upper MOSFET(VIN). ROCSET, an internal 20 A current source (IOCSET), and the upper metal oxide semiconductor field effect transistor (MOSFET) on res

39、istance (rDS(ON) set the converter overcurrent (OC) trip point according to this equation: IPEAK= )ON(DSrOCSETOCSET)R)(I(An overcurrent trip cycles the soft start function. VOUT This pin is not used and should be left open. VCCThis pin provides bias supply for the integrated circuit. Connect a well

40、decoupled 3.3 V supply to this pin. PHASE Connect this pin to the upper MOSFETs source. This pin is used to monitor the voltage drop across the upper MOSFET for overcurrent protection. RT Connect an external resistor from this pin to ground for frequency selection. Refer to RT versus frequency curve

41、 shown in figure 4 BOOT This pin provides ground referenced bias voltage to the upper MOSFET driver. A bootstrap circuit is used to create a voltage suitable to drive a logic level N-Channel MOSFET. A large (1 M) resistor should be connected from the pin to GND. The purpose of this resistor is to di

42、scharge the BOOT pin during a shutdown condition, SYNC/EN = LOW so that the gate drivers are quickly powered off by this bleed resistor. UGATE Connect this pin to the upper MOSFETs gate. This pin provides the PWM controlled gate drive for the upper MOSFET. This pin is also monitored by the adaptive

43、shoot-through protection circuitry to determine when the upper MOSFET has turned off. GND This pin represents the signal and power ground for the integrated circuit. Tie this pin to the ground island/plane through the lowest impedance connection available. LGATE Connect this pin to the lower MOSFETs

44、 gate. This pin provides the PWM controlled gate drive for the lower MOSFET. This pin is also monitored by the adaptive shoot-through protection circuitry to determine when the lower MOSFET has turned off. CMOP, FB COMP and FB are the available external pins of the error amplifier. The FB pin is the

45、 inverting input of the internal error amplifier and the COMP pin is the error amplifier output. These pins are used to compensate the control feedback loop of the converter. CPGND This pin represents the signal and power ground for the charge pump. Tie this pin to the ground island/plane through th

46、e lowest impedance connection available. SYNC/EN This is a dual function pin. To synchronize with an external clock, apply a clock with a frequency 1.1 to 2.0 times higher than the parts natural frequency to this pin. The device may be disabled by tying this pin to ground. In this shutdown mode, all

47、 functions are disabled and the device will draw 55 A supply current. FIGURE 2. Terminal connections - Continued.
