MP4432GL-Z is a type of DC DC Switching Regulators, a type of voltage regulators, one of the power management integrated circuits (PMICs) that are becoming increasingly popular in modern electronic systems.

Application Field

MP4432GL-Z can be used to drive N/MOSFETS, inductors, and opto-couplers. This makes it ideal for high-side and low-side switch applications, including boost, SEPIC, and flyback converters for both AC-DC and DC-DC controllers. The device is suitable for both low and intermediate power applications, providing efficiency, performance, protection and cost benefits for a variety of applications including 5V and 12V supplies, battery operated applications, phone chargers, and intelligent power supplies.

Working Principle

The device operates using a standard synchronous Buck configuration. It is designed to provide an adjustable output voltage as required by the system using a single external resistor. The circuit consists of a P-channel MOSFET (PFET) and an N-channel MOSFET (NFET) connected in series. The PFET is used to draw current from the input voltage source, while the NFET is used to control the output voltage. The output voltage is adjusted by varying the duty cycle of the NFET with respect to the PFET.

MP4432GL-Z provides various protection features to ensure the reliability and safety of the system. These include under-voltage lockout (UVLO), programmable over-voltage protection (OVP) using a voltage divider and a precision voltage reference (VREF), over-current protection (OCP), thermal shutdown (TSD), open-drain flag output indicators and an internal compensation circuit. The OCP is adjustable via an external resistor and a reference voltage. The device also features an adjustable soft-start function, programmable pull down resistor, high efficiency operating in either continuous or discontinuous modes, and an internal loop compensation.

In summary, the MP4432GL-Z is a highly integrated solution for DC DC Switching Regulators applications, providing performance, efficiency, protection and cost benefits for a variety of applications ranging from phone chargers to 5V and 12V supplies. The device’s various protection features make it an ideal choice for reliable and safe operation.
