Patent number: 11943658Abstract: A multi-protocol network and methods for operating the same are provided. The method begins with establishing a wireless-connection between a first transceiver in a first device and a second-transceiver in a second device using a wireless-protocol. First, wired-protocol packets and non-packet data are received and converted in the first device to second-packets compatible with the wireless-protocol by inserting synchronization-bits non-packet data in a preamble field. This is initiated by sensing arrival of the preamble without waiting for a start of data. The second-packets are transmitted from the first transceiver to the second, and converted to third-packets compatible with the wired-protocol by removing the synchronization-bits. Latency is improved by initiating/starting a packet to the wired controller before a data portion of the packet is received. The number of synchronization bits is selected so the second-packets are aligned and synchronized with wireless-protocol packets.Type: GrantFiled: September 24, 2021Date of Patent: March 26, 2024Assignee: Cypress Semiconductor CorporationInventors: Victor Simileysky, Kiran Uln, Saishankar Nandagopalan

Publication number: 20240063719Abstract: Systems and methods are provided to supply a voltage (Vcc) to a primary IC in a switch-mode-power-supply following startup. Briefly, an input voltage (VIN) coupled through a boost-inductor to a switch-pin of the IC is sensed by isolating a DC component (VDC_BSW) of the voltage and checking if VIN is greater than a minimum VIN (VIN_MIN) by comparing VDC_BSW to a starting reference voltage (VREF_START) in the IC. If VDC_BSW is greater than VREF_START, a boost-switch in the IC through which the switch-pin is coupled to ground is cycled on and off to alternately store and discharge energy in the boost-inductor, boosting Vcc. Thereafter, VIN is checked against a maximum input voltage by comparing VDC_BSW to a reference voltage (VREF), greater than VREF_START, and if VDC_BSW is greater than VREF, boost is turned off by turning off and ceasing to cycle the boost-switch, protecting the boost-inductor from current runaway.Type: ApplicationFiled: May 23, 2023Publication date: February 22, 2024Applicant: Cypress Semiconductor CorporationInventors: Qiong Zou, Soon Hwei Tan
