DC-DC преобразователи интегральные MAX17024ETD+T

ШИМ контроллер , динамический REFIN, 2В до 26В питание, 2.015В/1.5А выход, TDFN-14

The MAX17024ETD+T from Maxim Integrated Products is a single quick-PWM step-down controller with dynamic REFIN in 14 pin TDFN package. This PWM controller provides high efficiency, excellent transient response and high DC-output accuracy needed for stepping down high voltage batteries to generate low voltage core or chipset/RAM bias supplies in notebook computers. Maxim's proprietary Quick-PWM™ quick-response, 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. It includes a voltage controlled soft-start and soft-shutdown to limit input surge current, provide a monotonic power-up (even into a precharged output) and provide a predictable power-up time. It is used at notebook computers, I/O and chipset supplies, GPU core supply, DDR memory VDDQ or VTT, point-of-load Applications and Step-Down Power Supply.
