ADP3153 General Description
The ADP3153 is a highly efficient synchronous switching regulator controller and a linear regulator controller. The switching regulator controller is optimized for Pentium II and Deschutes
Processor applications where 5 V is stepped down to a digitally controlled output voltage between 1.8 V and 3.5 V. Using a 5-bit DAC to read a voltage identification (VID) code directly from
the processor, the ADP3153 uses a current mode constant offtime architecture to generate its precise output voltage.
The ADP3153 drives two N-channel MOSFETS in a synchronous rectified buck converter, at a maximum switching frequency of 250 kHz. Using the recommended loop compensation and guidelines, the ADP3153 provides a dc/dc converter that meets Intel's stringent transient specifications with a minimum number of output capacitors and smallest footprint. Additionally,
the current mode architecture also provides guaranteed short circuit protection and adjustable current limiting.
The ADP3153's linear regulator controller drives an external N-channel device. The output voltage is set by the ratio of the external feedback resistors. The controller has been designed for excellent load transient response.
