Описание

The MAX1627ESA+T is a high efficiency step-down DC-DC controller in 8 pin NSOIC package. The controllers deliver load current from 1mA to 2A. It supports adjustable outputs from 1.3V to 16V. Using an external MOSFET and current-sense resistor allows design flexibility and improved efficiencies associated with high performance P-channel MOSFETs. A unique, current-limited, pulse frequency modulated (PFM) control scheme gives this device excellent efficiency over load ranges up to three decades while drawing around 90µA under no load. This wide dynamic range optimizes device for battery powered applications where load currents can vary considerably as circuit block is turned on and off to conserve energy. Operation to a 100% duty cycle allows lowest possible dropout voltage and extends battery life. High switching frequencies & simple circuit topology minimize PC board area & component costs. It is used in minimum component DC-DC converters & 5V to 3.3V green PC applications.

• Supply voltage range is 3V to 16.5V
• Operating temperature range from -40°C to 85°C
• Reduce external components and total cost, tiny surface mount inductor
• 300KHz PWM switching reduces component size
• Reduce power dissipation, efficiency from 3mA to 2A loads is > 90% & low dropout voltage
• Reduce number of DC-DC controllers to stock, reduce system power consumption
• Maximum quiescent current is 90µA, maximum shutdown current is 1µA
• Operates reliably in adverse environment, soft-start limits start-up current
• Increase design flexibility, current limited control scheme
• External P-channel MOSFET allows output power of > 12.5W
