MAX662ACPA

The MAX662ACPA is an advanced DC-DC switching regulator from Maxim Integrated. This converter provides up to 1.35A of continuous output current in a compact 8-pin package. The device provides high efficiency, programmable switching frequencies, and industry-standard output voltages. The converter features an internal 1.2MHz switch, as well as adjustable input and output voltages.

The MAX662ACPA is especially suitable for applications where power savings and low power dissipation are of paramount importance. It is commonly seen used in embedded systems and their peripherals, such as in microprocessor-based systems, processors, automotive telematic systems, pocket-sized systems, and hand-held equipment. It is also found in applications in airplanes and satellites.

working principle

The DC-DC converter can be described as a switched capacitor working in an on/off manner or pulse-width modulation (PWM) mode. In the on/off state, the converter switches between its maximum input voltage and its minimum. The output voltage is determined by the ratio of the on time to off time.

In PWM mode, the converter switches between a high-voltage level and a low-voltage level. The output voltage is determined by the ratio of the width of the signal to its period. By varying the duty cycle of the PWM signal, the output voltage of the MAX662ACPA can be adjusted.
