RT9245B Product details

General Description

RT9245B is a multi-phase buck DC/DC controller integrated with all control functions for AMD K8 CPU or Intel® GHz CPU which is VRD10.x-compliant. The RT9245B could be operated with 2, 3 or 4 buck switching stages operating in interleaved phase set automatically. The multiphase architecture provides high output current while maintaining low power dissipation on power devices and low stress on input and output capacitors. The high equivalent operating frequency also reduces the component dimension and the output voltage ripple in load transient.



Features

Multi-Phase Power Conversion with Automatic Phase Selection

6-bits VRD10.x or 5-bit K8 DAC Output with Active Droop Compensation for Fast Load Transient

Smooth VCORETransition at VID Jump

Power Stage Thermal Balance by DCR Current Sense

Hiccup Mode Over-Current Protection

Programmable Switching Frequency (50kHz to 400kHz per Phase), Under-Voltage Lockout and SoftStart

High Ripple Frequency Times Channel Number

28-TSSOP Package

RoHS Compliant and 100% Lead (Pb)-Free



Applications

Intel® Processors Voltage Regulator : VRD10.x and AMD K8

Low Output Voltage, High Current DC-DC Converters

Voltage Regulator Modules
