Introduction

MAX8868EUK50+T is a mono-rail DirectFET power management IC (PMIC) with a low dropout linear voltage regulator (LDO), an integrated voltage supervisor, a powerful buck regulator, and an adjustable current-limit circuit. This PMIC also offers an integrated power-on-reset (POR) function and an additional input voltage monitor which enable system-level diagnostics. This article will introduce the application field and working principle of MAX8868EUK50+T.

Application Fields

MAX8868EUK50+T can help engineers design battery-powered mobile consumer electronic devices. DirectFET\'s advanced RDS(ON) technology helps reduce heat generation; the LDO provides a low noise output voltage and power-on-reset (POR) function improves system reliability. The built-in advanced safety features enable the system to operate under the harshest power conditions. It is suitable for applications such as notebook PCs, PDAs, digital cameras, mobile phones, audio players, etc.

Working Principle

The MAX8868EUK50+T utilizes five integrated circuits in a single package. 1. Low Dropout Regulator: It provides low dropout performance and precise load regulation. The LDO has an adjustable output voltage range of 0.9V to 5V. 2. High-Performance Buck Regulator: It supports up to 4A of output current with good transient performance. The output voltage can be regulated from 0.6V to VIN.3. Voltage Supervisor: The integrated voltage supervisor provides sensing of VOUT and VIN, and asserts its output when input power is detected as low. 4. Current Limiting Circuit: The current limiting circuit is adjustable and allows precise control of the maximum output current. 5. Internal POR: The integrated power-on-reset (POR) function ensures the system starts safely and quickly after the power is on.The MAX8868EUK50+T is capable of supplying 5V at 3A, 4A and 5A output current with 0.9V-5V adjustable voltage. The total power dissipation is approximately 30W and temperature rise is about 35°C. The device has a low dropout voltage of only 1V and an output noise density of up to 500nV/√Hz.

Conclusion

MAX8868EUK50+T provides a cost-effective and reliable power management solution for mobile consumer electronic devices. It features an integrated low dropout regulator, a high performance buck regulator, a voltage supervisor, a current limiting circuit, and an internal POR. These features enable the MAX8868EUK50+T to operate at 5V, 3A, 4A, 5A output current; 0.9V-5V adjustable voltage; a low dropout voltage of only 1V; and an output noise density of up to 500nV/√Hz.
