Overview

19-2795; Rev 0; 7/03 Low-Cost, Wide Input Range, Step-Down Controllers with Foldback Current Limit General Description The MAX8545/MAX8546/MAX8548 are voltage-mode pulse-width-modulated (PWM), step-down DC-DC controllers ideal for a variety of cost-sensitive applications.
They drive low-cost N-channel MOSFETs for both the high-side switch and synchronous rectifier, and require no external current-sense resistor.
These devices can supply output voltages as low as 0.
8V.
The MAX8545/MAX8546/MAX8548 have a wide 2.
7V to 28V input range, and do not need any additional bias voltage.
The output voltage can be precisely regulated from 0.
8V to 0.
83 x VIN.
These devices can provide efficiency up to 95...
