| Description | The device is a power supply controller specifically designed to provide a high performance DC/DC conversion for high current microprocessors. A precise 5 bit digital to analog converter (DAC) allows ... |
| Features |
a 15MHz gain-bandwidth product and 10V/ ms slew rate which permits high converter bandwidth for fast transient performance. The resulting PWM duty cycle ranges from 0% to 100%. The device protects against over-current conditions entering in HICCUP mode. The device monitors the current by using the rDS(ON) of the upper MOSFET which eliminates the need for a current sensing resistor. The device is available in SO20 package.
Oscillator
The switching frequency is internally fixed to 200kHz. The internal oscillator generates the triangular waveform for the PWM charging and discharging with a const... |
