Product Description
The RT8209A/B/C PWM controller provides high efficiency, excellent transient response, and high DC output accuracy needed for stepping down high voltage batteries to generate low voltage CPU core, I/O, and chipset RAM supplies in notebook computers.
The constant-on-time PWM control scheme handles wide input/output voltage ratios with ease and provides 100ns "instant-on" response to load transients while maintaining a relatively constant switching frequency.
The RT8209A/B/C achieves high efficiency at a reduced cost by eliminating the current-sense resistor found in traditional current mode PWMs. Efficiency is further enhanced by its ability to drive very large synchronous rectifier MOSFETs. The buck conversion allows this device to directly step down high voltage batteries for the highest possible efficiency. The RT8209A/B/C is intended for CPU core, chipset, DRAM, or other low voltage supplies as low as 0.75V. The RT8209A is in a WQFN-16L 3x3 package, the RT8209B is in a WQFN-14L 3.5x3.5 package and the RT8209C is available in a TSSOP-14 package.
