This datasheet also covers the G5617A-GlobalMixed variant, as both devices belong to the same programmable output high-speed step-down controller family and are provided as variant models within a single manufacturer datasheet.
General Description
G5617A/G5617B PWM controller uses constant on-time control scheme to handle wide input/output voltage ratios with ease and provides 100ns “instant-on” response to load transients while maintaining a relatively constant switching frequency.
Note: The manufacturer provides a single datasheet file (G5617A-GlobalMixed-modeTechnology.pdf) that lists specifications for multiple related part numbers.
