Overview
| Topology | Flyback Converter |
| Input voltage | 90-440 V |
| Output 1 | 16 V / 1 A |
| IC revision | 1 |
Description
The device is an off-line converter with an 800 V avalanche ruggedness power section, a PWM controller, user defined overcurrent limit, protection against feedback network disconnection, hysteretic thermal protection, soft start up and safe auto restart after any fault condition.Advance frequency jittering reduces EMI filter cost. Burst mode operation and the devices very low consumption both help to meet the standard set by energy saving regulations.
Features
- Full single phase meter development kit based on the STCOMET smart meter system-on-chip
- Complete power line communication (PLC) reference design suitable to implement several PLC protocols in CENELEC, ARIB and FCC bands
- Metering in compliance with EN 50470-1, EN 50470-3, IEC 62053-2x, up to class0.2
- Up to 3 independent measurement channels for mains voltage and input/output current
- Two LEDs for active and reactive energy signaling
- Two tamper buttons
- ARM® 32-bit Cortex®-M4F CPU embedded in the STCOMET device for system management and application host controller
- 86 available GPIOs, general purpose LEDs and buttons and LCD on strip module
- Digital connector for 3-phase metering extension with the EVALSTPM34
- Relay driving circuit for unipolar and bipolar relay based on ST L2293Q monolithic driver device
- Off-line switching mode power supply based on ST VIPER26H isolated flyback reference design (+ optional 8 - 15 V input available for laboratory tests)
- JTAG debug over isolated USB host interface for connecting to a PC (J-Link OB)
- Dual UART over isolated USB host interface for connecting to a PC
- Suitable for CENELEC EN50065 and FCC part 15 compliant applications.
Typical applications
- Power metering
- Auxiliary power supply for appliances / SMPS for set-top boxes, DVD players and recorders
- LED drivers
- 3 kW interleaved PFC refdesign based on a digital controller and includes a separate power board, control board and programming board
