Maxim Integrated\'s MAX8739ETP+ is a monolithic buck regulator designed to provide advanced features and optimized performance. The device is designed to convert a 3.2V to 5.5V input voltage range to a 0.6V to 5V output voltage range. It integrates two fast-transient-response buck regulators that can operate in either single-channel (1-phases) or dual-channel (2-phases) modes. The device also features an adjustable soft-start circuit to minimize current surges during start-up, a temperature-independent current limit, and a frequency-hopping feature to extend battery life by reducing current ripple.The MAX8739ETP+ is a highly integrated monolithic buck regulator suitable for portable applications such as smartphones, tablets, and digital cameras. Typical applications include step-down voltage regulation, battery charging, and USB power conversion. Additionally, the device is also well suited for PC/server applications, point-of-load regulation, and other low-output-voltage applications.The MAX8739ETP+ device combines two buck regulators, one with a single-phase mode and the other with a two-phase mode. The two-phase buck regulator provides more power with less noise and faster transient response when compared to single-phase buck regulators. The single-phase mode is ideal for small output power requirements and lower ripple requirements. The two-phase mode can provide increased performance for high-current-load conditions and faster transient response.The MAX8739ETP+ utilizes a simple architecture that allows for improved efficiency and faster response times. The architecture consists of a low impedance power distribution bus, two low-dropout (LDO) linear regulators, two buck regulators and a control logic block. The low impedance power distribution bus distributes the input power to the two buck regulators, providing better voltage regulation and noise isolation. The two LDOs provide precise output voltage regulation and a temperature-independent current limit and adjustable soft-start circuit for safe start-up.The control logic block controls the two-phase operation of the device, providing faster transient response and improved noise rejection. The control logic block also contains adjustable dead-time control, frequency synchronization, and frequency hopping, allowing for power savings and better noise rejection. Additionally, the MAX8739ETP+ can operate from a 3.2V to 5.5V input voltage range and generate an output voltage of 0.6V to 5V.In conclusion, the MAX8739ETP+ provides a comprehensive solution for efficient voltage regulation in a wide variety of applications such as smartphones, tablets, digital cameras, PC/servers, and other low-output-voltage applications. The device features two-phase buck regulators, adjustable soft-start, temperature-independent current limit, frequency synchronization, and frequency hopping, enabling improved efficiency and faster transient response times. The MAX8739ETP+’s unique combination of two buck regulators and two LDOs provides greater output power and improved regulation while occupying minimal board space.
