TIDM-ETHERNET-BOOTLOADER: This design describes how to use Ethernet module to transfer the firmware image and program it into flash on Hercules MCU. The Ethernet bootloader is based on TFTP (Trivial File Transfer Protocol) which is a file transfer protocol notable for its simplicity. And it is a small piece of code that can be programmed at the beginning of the flash to act as an application loader as well as an update mechanism for applications running on a Hercules microcontroller.
PMP7770: It is an offline AC-DC LED driver. It has TRIAC dimming capability. It is basically a low side buck which has valley filled PFC. It takes an input voltage of 120V AC. This circuit uses LM3445 which is an adaptive constant off-time AC/DC buck (step-down) constant current controller designed to be compatible with Traic dimmers.
PMP8812: This design is a 12V/2.1A synchronous flyback converter for high efficiency PoE applications. The TPS23752 combines the Powered Device and PWM controllers in one package. Additional features are synchronous rectifier disable for improved light load efficiency and support for ulta low power sleep mode.
PMP9013: The PMP9013 is an IEEE802.3at, Type 2 compliant, high-efficiency synchronous flyback converter (5V @4.5A) with sleep mode used for PD design in PoE applications. The reference design has the ability to allow an external adapter to supply power to the board if PoE power is not available.
