Overview
19-2286; Rev 1; 9/03 MAX1966/MAX1967 Low-Cost Voltage-Mode PWM Step-Down Controllers General Description The MAX1966/MAX1967 are voltage-mode pulse-widthmodulated (PWM), step-down DC-DC controllers that are ideal for a variety of cost-sensitive applications.
They drive low-cost N-MOSFETs for both the high-side switch and synchronous rectifier and require no external Schottky power diode or current-sense resistor.
Shortcircuit and current-limit protection is provided by sensing the drain-to-source voltage on the low-side FET.
Both devices can supply outputs as low as 0.
8V and are well suited for DSP cores and other low-voltage logic.
The MAX1966 has an input range of 2.
7V to 5.
5V while the MAX1967 has an input range of 2.
7V to 28V.
In ultra-low-cost designs, the MAX1966/MAX1967 can provide efficiency exceeding 90% and can achieve 95% efficiency with optimized component selection.
The MAX1966/MAX1967 operate at 100kHz and accommodate aluminum electrolytic capacitors and powdered-iron ...
