描述
The Himalaya series of voltage regulator ICs, power modules, and chargers enable cooler, smaller, and simpler power supply solutions. MAX17623 and MAX17624 are high-frequency synchronous Himalaya step-down DC-DC converters with integrated MOSFETs and internal compensation. MAX17623 and MAX17624 have an input-voltage range of 2.9V to 5.5V, supports up to 1A, and output voltage can be adjusted from 0.8V to 3.3V. The MAX17623 and MAX17624 employ peak-current mode control architecture under steady-state operation. To reduce input-inrush current, the devices offer 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 operates at a fixed 4MHz switching frequency. MAX17623 offers 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.
