PMIC - Voltage Regulators - DC DC Switching RegulatorsThe MAX643ACSA+T is an integrated switching regulator designed for DC-DC conversion. It is a part of the versatile MAX6 family of integrated circuits from Maxim Integrated Products. It is designed for low voltage, low quiescent current applications. It features low-input-voltage and high-output-voltage capability. The device is configured as a buck-boost converter that operates from an input voltage range from 2.2 V to 18V and an output voltage range from 1V to 15V.The MAX643ACSA+T is a synchronous, lightweight switching regulator with an output ripple of less than 10mVrms over the load change. It has a 2.2nF capacitor integrated on board that acts as an output filter. It has an ultra-low quiescent current of only 2.2mA, enabling reduced system power consumption. It also has a fast transient response with a bandwidth of 2 MHz, ideal for high-density applications. The device also features a wide output voltage range, a programmable power-good voltage, and an adjustable soft-start and slew rate. The wide output voltage range ensures compatibility with all types of applications, while the adjustable soft-start and slew rate are beneficial for circuit noise reduction. The MAX643ACSA+T also features a power-saving sleep mode and auto-skip mode, which enables it to improve system efficiency and reduce standby power.The MAX643ACSA+T operates in both feedback and open-loop modes for flexibility. In feedback mode, the output voltage is regulated to a stable value set by the voltage reference. In open-loop mode, a resistive divider in the ADJ pin can be used to set the output voltage. The device also features programmable current limit and thermal shutdown. The current limit can be programmed through an external resistor, while the thermal shutdown is set by the junction temperature.The MAX643ACSA+T is ideal for use in low voltage, high current applications, such as wireless charging, USB charging, portable battery charging, PoE systems, industrial supplies and general purpose DC-to-DC converters. It is also suitable for a variety of automotive applications, such as electric power steering, vehicle electronics, battery management and fuel cell systems.The MAX643ACSA+T is available in a variety of packages, including a 6-lead SOT23-6 and 8-pin uSOIC formats. It is also available with a lead frame package that enables higher current operation without additional heatsinking. The device is also RoHS-compliant and has an operating temperature range from -40°C to +85°C.To summarize, the MAX643ACSA+T is a versatile and lightweight switch mode power supply that offers low-input and high-output voltage capability, low quiescent current, and fast transient response. It is suitable for use in low voltage, high power applications, such as wireless and USB charging, automotive electronics and industrial supplies. It is available in a variety of packages with an operating temperature range of -40°C to +85°C and is RoHS-compliant.
