The AIC1569A is a 5-bit DAC, synchronous PWM power regulator. It is compatible with HIP6004 and features simple voltage-mode PWM control, dual N-channel MOSFET synchronous drive, and fast transient response.
The AIC1569A is a high-power, high-efficiency switching regulator controller optimized for high-performance microprocessor applications. It features simple voltage-mode PWM control and drives dual N-channel MOSFETs in a standard synchronous buck topology. The device includes an internal 5-bit Digital-to-Analog Converter (DAC) that adjusts the output voltage from 2.0V to 3.5V in 0.1V increments, with precision regulation within +1% over temperature and line shifts.
Key features include a programmable oscillator running up to 350KHz, adjustable current limit without an external sense resistor, and full 0% to 100% duty ratio capability. The controller provides comprehensive protection capabilities such as over-voltage trip, short circuit protection, and power-good output voltage monitoring.
