ISL6525规格书详情
The ISL6525 provides complete control and protection for a DC-DC converter optimized for high-performance microprocessor applications. It is designed to drive two N Channel MOSFETs in a synchronous-rectified buck topology. The ISL6525 integrates all of the control, output adjustment, monitoring and protection functions into a single package. A programmable delay time for the PGOOD signal makes it especially suitable for the VTT regulation in VRM8.5 applications.
The output voltage of the converter can be precisely regulated to as low as 1.20V, with a maximum tolerance of ±1 over temperature and line voltage variations.
The ISL6525 provides simple, single feedback loop, voltage mode control with fast transient response. It includes a 200kHz free-running triangle-wave oscillator that is adjustable from below 50kHz to over 1MHz. The error amplifier features a 15MHz gain-bandwidth product and 6V/µs slew rate which enables high converter bandwidth for fast transient performance. The resulting PWM duty ratio ranges from 0 to 100.
The ISL6525 protects against over-current conditions by inhibiting PWM operation. The ISL6525 monitors the current by using the rDS(ON) of the upper MOSFET which eliminates the need for a current sensing resistor.
