40V, 3.5A Monolithic Step-Down Switching Regulator
Features
to GND, Set frequency to 80 kHz)
| Description The PL82052 is a monolithic synchronous buck regulator with wide operating input voltage range from 4.6 to 33V. Current mode control with internal slope compensation is implemented to reduce component count. PL82052 also features a light load pulse skipping mode, which allows for a power loss reduction from the input power supply to the system at light loading. The switching frequency of the converters can be set from 80 kHz to 2 MHz with an external resistor. Frequency spread spectrum operation is introduced for EMI reduction. A cycle-by-cycle current limit with frequency fold back protects the IC at over loading condition. PL82052uses external compensation, This simplifies the loop design for different frequencies |
