NCP1077BAP130G application field and working principle

NCP1077BAP130G is designed to provide advanced power management features and innovative performance benefits. The device is a PMIC (Power Management IC), belonging to AC/DC converters, offline switchers category. It is specifically designed for energy saving applications in various electronic products.The device is capable of providing accurate and powerful load drive for a wide range of sub-circuit components. It has an on-die Charge Pump that can provide +5V output (5V/15mA) and it also features an on-chip Error Amplifier and Variable Frequency Oscillator (VFO). The device also features a modern digital delay-timer circuitry, designed to accurately regulate the output current and frequency. NCP1077BAP130G is designed to bridge the gap between cost and performance. It has a low cost and is small in size and therefore it can be easily implemented in various smaller battery powered applications. The device supports a wide operating voltage range of 3V to 6V, so it can be used in a broad range of applications. It also has built-in soft-start to reduce input inrush and reduce current surges.The device can also perform high-speed switching of loads up to 50MHz. As a result, it can be used to design offline switch mode power supplies (SMPS) with very high efficiency and low power consumption. It also has built-in thermal shutdown and current limiting circuitry, which further adds to its safety features.The device has two P-Channel Mosfets, two N-Channel Mosfets and one voltage regulator. The four Mosfets are used to drive the output current while the voltage regulator maintains the output voltage. The two N- Channel Mosfets are responsible for power conversion while the two P-Channel Mosfets provide voltage/current amplification and protection.The device also features pulse width modulation (PWM) architecture which controls the switching of the Mosfets and frequency of the output. The duty cycle of the PWM is adjustable and can be set to a value between 1μs and 6μs. The frequency range of the output current is adjustable to between 300kHz and 500kHz. Overall, the NCP1077BAP130G PMIC provides advanced power management features and innovative performance benefits. It is an ideal choice for numerous energy saving applications thanks to its low cost and small size. Its on-die Charge Pump, Error Amplifier, VFO and PWM architecture ensures efficient control and load drive of sub-circuits without compromising safety. Furthermore, its built-in thermal shutdown and current limiting circuitry adds to its impressive list of safety and performance features.
