Maxim's MAX17504, a high-efficiency high-voltage synchronous step-down
converters are now available from Mouser stock. The device comes with dual
integrated MOSFETs and operate over a 4.5V to 60V input. It delivers up to
3.5A and 0.9V to 90% VIN output voltage. Built-in compensation across the
output voltage range eliminates the need for external components. The
feedback (FB) regulation accuracy over -40C to +125C is ±1.1%.
The device features a peak-current-mode control architecture with a MODE
feature that can be used to operate the device in pulse-width modulation,
pulse-frequency modulation, or discontinuous mode control schemes.
Pulse-width modulation operation provides constant frequency operation at
all loads, and is useful in applications sensitive to switching frequency.
