The MAX1844EEP from Analog Devices is a pulse-width modulation (PWM) controller engineered for high-efficiency, low-voltage power supplies in notebook computers. It is suitable for generating CPU core, chipset, or RAM supplies as low as 1V.
This controller utilizes Maxim's proprietary Quick-PWM™ control scheme, providing a 100ns instant-on response to load transients and maintaining a relatively constant switching frequency. It supports a wide input voltage range from 2V to 28V and offers adjustable output voltages from 1V to 5.5V, with fixed options for 1.8V and 2.5V. The device also features 1% output voltage accuracy over line and load conditions.
Designed for flexibility, the MAX1844EEP can be configured for single-stage buck conversion for maximum efficiency or two-stage conversion for minimum physical size. It includes features such as adjustable overvoltage and undervoltage protection, a 1.7ms digital soft-start, and an accurate current-limit option. The controller is available in a 20-pin QSOP package, suitable for surface mount applications.
Key features include ultra-high efficiency, Quick-PWM with 100ns load-step response, and the ability to drive large synchronous-rectifier MOSFETs. It operates within a temperature range of -40°C to 85°C.
