With the rapid development of information technology and the continuous deepening of market demand for automation and intelligence, the performance of power integrated circuits (PMICs) is becoming more and more important. PMICs can be used in various applications, such as mobile phones, tablet computers, industrial control systems and automotive systems. PMICs are not only used to complete the power management functions in electrical equipment products, but also improve the system\'s flexibility, efficiency and cost-effectiveness.

PMICs generally include Voltage Regulators and DC DC Switching Regulators. PMICs Voltage Regulators are mainly used to improve the linear regulation accuracy of the output voltage; DC DC Switching Regulators are mainly used for step-down and step-up voltage conversion. AP65452SP-13 belongs to PMICs DC DC Switching Regulators.

AP65452SP-13 is a single-channel step-down DC DC Switching Regulator. It provides high efficiency, low noise and small size. The main features of AP65452SP-13 are output current of up to 2A for long time and internal soft start for over-current protection. The input voltage of AP65452SP-13 varies between 2.3V and 5.5V, and the output voltage can be adjustable to 0.7V~3.3V. AP65452SP-13 can achieve the full load efficiency of up to 90%.

AP65452SP-13 has a wide range of applications, such as notebook computers, desktop computers, netbooks, tablet PCs, consumer electronics, system board voltage modules, cellular phones, cordless phones, digital cameras, etc. Moreover, one AP65452SP-13 can replace four AP60342P-16 products.

AP64452SP-13 works according to the fixed frequency, PWM (Pulse Width Modulation) control mode. The working principle is mainly divided into three steps. First, adjust the internal reference voltage during startup time. Second, detect the output voltage and internal oscillator clock frequency to control the output voltage. Third, adopt the voltage feedback loop to generate the pulse width modulated drive signal for controlling the power switch.

AP65452SP-13 has integrated high- and low-side power MOSFET switches, which optimize the efficiency and reduce the external components. Its internal high switching frequency reduces the output capacitor size and cost, and the device can achieve excellent efficiency performance and eliminate EMI. On the other hand, AP65452SP-13 employs spread spectrum modulation to further reduce EMI. The other specialty of AP65452SP-13 is its adaptive on-time control, which uses advanced ripple cancellation technology to optimize the load transient response.

AP65452SP-13 enables designers to develop high-efficiency, low-noise LED lighting system adaptors and low-power, low-noise microprocessor power supplies with improved EMI performance. It also can provide a more cost-effective solution for developing high-density power systems. The product features extraordinary performance and superior reliability, making it the best choice for a variety of applications.
