PMIC - Voltage Regulators - Special Purpose

The MAX720CSE from Maxim Integrated is a complete step-down power-supply solution for microprocessors, FPGAs and other digital integrated circuits. It is designed to supply a regulated output voltage for next-generation microprocessors and other microelectronic mechanisms. The device is optimized for fast transient response, low noise and low output voltage so that system performance is enhanced. This device is suitable for a variety of applications since it has a wide input voltage range, an adjustable output voltage and an integrated switching regulator. In addition, it is available in a low-profile 16-pin TQFN (Thermo-Quadratic Flat No-Lead) package.

The MAX720CSE operates with a wide input voltage range of 2.8V to 5.5V and provides an adjustable regulated output of 2.8V to 5.5V. The output voltage is continuously adjustable, up to 0.5V from programmed reference setting and is monitored with a precision voltage reference. This device utilizes automatic synchronization between the external clock and the internal clock, so that it is suitable for applications requiring fast transient response and low output voltage. The device also has the capability to survive input voltages greater than the maximum rated input voltage.

The MAX720CSE utilizes a peak-current-mode control architecture, has an adjustable switching frequency from 100kHz to 1MHz, and a wide operating temperature range from -40°C to +125°C. This device also supports a sleep state and a power-down mode, which provides improved system-level power savings. The device has an input under-voltage lockout (UVLO) and a precision power-on reset circuit, allowing the system to be in power-saving mode.

The MAX720CSE has a typical application field which includes personal computers and laptops, as well as consumer audio and video products, point-of-sale systems, industrial dimming and lighting control systems and other applications that require a polyphase DC-DC converter with low output voltage and fast transient response.

In summary, the MAX720CSE is a complete polyphase step-down power-supply solution for microprocessors, FPGAs and other digital integrated circuits. It provides adjustable output voltage, fast transient response and low noise supply for the system. Its wide input voltage range and point-of-sale applications make it ideal for next-generation microprocessor-driven systems.
