ADM8660ANZ Application Field and Working Principle

The ADM8660ANZ is a three-terminal synchronous buck PWM controller which integrates high and low-side MOSFETs in a DC/DC switching regulator. It is the chip of choice for designing various micro-processor voltage conversion circuits with low EMI. It is ideal for boosting or bucking microprocessors power supply voltages in advanced CPU motherboards, such as Intel Pentium 4s, or AMD Athlons.

The ADM8660ANZ provides excellent efficiency and tight regulation over a wide input voltage range. It allows ±1% accurate output voltage setting over the entire operating range without requiring external resistors. The chip’s high-side MOSFET can switch up to 60V, while the low side MOSFET can switch up to 36V. Additionally, this IC has several features to minimize power dissipation, including pulse width modulation (PWM) energy recycling, pre-bias or smooth start-up, and thermal shutdown with hysteresis. The chip also offers active input current sensing, remote sensing, and adjustable soft-start.

The ADM8660ANZ is available in a 28-pin SSOP package, and operates over a 10V dynamic input voltage range from 5.5V to 16V. When used with a bootstrap device, its maximum output voltage is limited to 18V. The switch frequency is adjustable from 200kHz to 600kHz via an external resistor, and may be synchronized using an external clock. Finally, the output voltage tolerance is ±1.5% at room temperature.
