Both devices include a high-efficiency, fixed-frequency, step-down regulator. The low-cost, all N-channel, synchronous topology enables operation with efficiency as high as 93%. High-frequency operation allows the use of small inductors and capacitors, resulting in a compact solution. The MAX1530 includes three linear regulator controllers and the MAX1531 includes five linear regulator controllers for supplying logic and LCD bias voltages. A programmable startup sequence enables easy control of the regulators.
