MAX640EPA+ is a step-up/step-down switching voltage regulator manufactured by Maxim Integrated. It is mainly used to translate battery voltages of 2.3V-5.5V to an output voltage of up to 5.5V and to provide a short circuit protection. This voltage regulator has a typical quiescent current of 5mA, which is low compared to the traditional linear regulators and is suitable for portable devices.
Application Field
MAX640EPA+ is widely used in many applications such as LED driving, hand-held terminals, PDAs, cellular phones, digital still cameras etc. It can be used to drive both the high brightness LEDs and the low current LEDs, thus is a great choice for battery powered equipment.
Also, MAX640EPA+ is featured with its low stand-by current that makes it a great system solution for portables. The regulator can be shut down and resumed at any time, thus greatly helping to prolong the battery life. Moreover, it offers a wide input voltage range, excellent load regulation, fast transients and a 2A internal switch.
Working Principle
The principle of MAX640EPA+ is based on a pulse mode inductor-based current regulator loop with a frequency modulation regulating scheme. The frequency is adjusted over a wide range for the voltage regulation, to achieve the best performance. The output voltage is adjusted by the control loop with a voltage error amplifier.
The constant frequency, current mode design ensures fast line/load transient response, while the 2A internal switch is able to support large load applications. The additional current limit protection prevents the device from damage caused by overload or short circuit. The thermal shutdown prevents the device from operating at elevated temperature.
Summary
To summarize, MAX640EPA+ is a step-up/step-down switching voltage regulator manufactured by Maxim Integrated. It features a wide input voltage range, excellent load regulation, fast line/load transient response, a low stand-by current, and a 2A internal switch. It is widely used in many applications such as LED driving, hand-held terminals, PDAs, cellular phones, and digital still cameras etc. The working principle of MAX640EPA+ is based on a pulse mode inductor-based current regulator loop with a frequency modulation regulating scheme. Thus, it is an ideal choice for battery powered equipment which requires fast line/load transient response and high current output.
