Part Number: TPS610985
I am currenly using the high efficiency converter in a uPwr application operating from a 1.5V battery. I need to be able to shut down the input power, or enable the input power when needed. My application is now moving from 10K-100K volumes to 100K-1M unit volumes. Similar circuits that exist for OMAP and related PMIC controllers, it would be useful if a version that implemented a high-side switch and enable logic combined with the TPS61 series converters existed. It takes a fair bit of discrete transistor logic to run in 0.7V-2V domain (a PMOS high side sw to start, a NMOS source follower in parallel and glue, draws 0.1uA in shutdown, 5uA during operation). Love to hear from a PMIC product manager to discuss.
Thanks
