Most power management systems require a power source to meet varying load conditions. The MAX1636EAP + DC to DC Controller is an ideal solution for a wide variety of power management applications. The device allows a wide input voltage range of up to 40V and provides a step-down switching regulator with excellent efficiency over the full range. The device can be used to provide a single output or multiple outputs to meet a variety of needs, and includes a variety of power-saving and fault protection features.

The MAX1636EAP + is an advanced switching regulator controller that is designed for high efficiency and robust performance. The device is capable of providing voltage regulation and can supply up to 10A of output current with very low overshoot and ripple. It features an adaptive on-time control topology that optimizes the most efficient operation of the switching regulator in a wide range of load conditions. It has a wide speed range of 4 kHz to 1.2 MHz, which can be adjusted with an external resistor, and is programmed with a switching frequency from 400 kHz to 1.6 MHz.

The device includes an internal current source that is adjustable to supply a precise voltage setting regardless of output voltage ripple and load conditions. The control circuitry includes a low quiescent current, high efficiency pulse-width modulation controller that is programmed with a 0.5V to 4V detection voltage range. The device also includes an internal buffered reference to enable precise output voltage regulation. Moreover, the use of synchronous rectification provides higher efficiency in the regulating process.

The MAX1636EAP + delivers protection features such as thermal shutdown and short-circuit protection. Thermal shutdown switches off the IC in overheating conditions that might damage it. Short-circuit in external MOSFETS will be detected by the internal current limit which stops switching. Furthermore, the device can be configured in a single output configuration where its open loop voltage regulation accuracy is about ±2%, or it can be configured for dual output with up to ±5% accuracy.

The MAX1636EAP + is an ideal power management solution for a wide range of applications. The device is suitable for automotive, industrial, and consumer applications, and provides an extremely efficient and robust solution for regulating power source voltages. The device is also suitable for low-noise applications that require low ripple and overshoot. The device is available in a small 10-pin, 3x3mm, TDFN package that makes it suitable for space-constrained designs.
