Several operating modes are available: peak current-mode control, pulse-width modulation (PWM), pulse-frequency modulation (PFM) and discontinuous-conduction mode (DCM) to enable high efficiency under light load conditions. Housed in a 32 pin, 5 mm by 5 mm TQFN package supporting a wide operating -40° to 125° C temperature range.
Some other specifications and features include
- Independent input-voltage pins for each input
- Peak efficiency of 90.3 percent
- 5.2 uA shutdown current
- Hiccup-mode overload protection
- Over-temperature protection
The MAX17524 is suitable for many applications including base station power supplies, general purpose point-of-load and high-voltage single board systems, among others.
