... V. This 10-pin device provides an optimal level of integration to reduce size and cost of the power supply. The NCP1588 provides a 1.5 A gate driver design and an internally set 300 kHz oscillator. In addition to the 1.5 A gate drive capability, other efficiency enhancing features of the gate driver include adaptive non-overlap circuitry ...

... PWM logic and both HS-FET and LS-FET are turned off. Power has to be recycled to exit out of the overcurrent fault. The minimum turn-on time of the LS-FET is set to be 500 ns. NCP1588 allows to easily program an Overcurrent Threshold ranging from 550 mV, simply by adding a resistor (ROCSET) between LG and GND. During a short period of time following V ...

... Overvoltage Feedback and Compensation The NCP1588 allows the output voltage to be adjusted from 0 5.0 V via an external resistor divider network. The controller will try to maintain 0 feedback pin. Thus resistor divider circuit was placed across the feedback pin the controller will regulate the output ...
