Analog Devices Inc. MAX17623/MAX17624 Step-Down Converters
Analog Devices Inc. MAX17623/MAX17624 Step-Down Converters are part of the Himalaya series of products that enable cooler, smaller, and simpler power supply solutions. The MAX17623 and MAX17624 are high-frequency converters with integrated MOSFETs and internal compensation. The components offer an input voltage range of 2.9V to 5.5V, support up to 1A, and can be adjusted from 0.8V to 3.3V.
ADI MAX17623/MAX17624 Step-Down Converters employ a peak-current mode control architecture under steady-state operation. To reduce input-inrush current, the converters deliver a fixed 1ms soft-start time. Both devices feature selectable PWM for fixed-frequency operation or PFM mode for better efficiency at light loads. When PWM mode is selected, MAX17623 operates at a fixed 2MHz switching frequency, and MAX17624 runs at a fixed 4MHz switching frequency. MAX17623 supports output voltages from 0.8V to 1.5V, and MAX17624 offers output voltages from 1.5V to 3.3V.
The MAX17623 and MAX17624 devices are available in a compact 8-pin, 2mm × 2mm TDFN package.
