The TIDA-01344 reference design is a 24W, automotive 48V battery front-end power supply that generates 12V from a wide input range of 10V to 80V DC, up to 100V transient for LV148 standard compliance. The system consists of EMI filters for CISPR 25 compliance and circuit protection for clamping high voltage transients to safe levels for downstream circuitry. The fly-back controller implements primary side regulation with no optocoupler, allowing for extended life time and smaller board design, and the fly-back transformer is designed and qualified as automotive AEC-Q200 Grade 1.
Возможности:

Wide Vin flyback converter over the input voltage of 10V to 80V DC, 100V transient, output voltage 12V and current up to 2A Protection for clamping high voltage transients to safe levels for downstream circuitry Automotive AEC-Q200 Grade 1-qualified transformer design Primary side regulation with no optocoupler for extended lifetime and compact board design Tested for CISPR25-conducted EMI (Class 5)

This reference design is an automotive, 400-W, phase-shifted full-bridge converter which generates the 12-V output from a 48-V car battery. The enhanced phaseshifted full-bridge controller implements programmable delays which ensure zero voltage switching (ZVS) over a wide range of operating conditions. The output implements synchronous rectification, which enables fast transient response and a high loop bandwidth. The system regulates 12 V at no load with less than 100 mW of standby power. Pseudo isolation is achieved through a transformer to prevent the 48-V battery from being shorted to the secondary side. The half-bridge gate drivers can withstand a maximum boot voltage of 120-V DC.
Возможности:

Phase shifted full bridge converter over the input voltage of 36V to 60V DC, output power up to 400W Extendable to 500W with heatsinking, easy to customize per customer needs Soft-switching, phase-shifted full bridge using UCC28951-Q1 analog controller, Grade 1 Regulated 12V output with 36V to 60V input and with <100mW standby power at no load Adaptive delay control for high efficiency across load range

This reference design is an excitation amplifier and analog front end for resolver sensors. The design implements only discrete components and standard operational amplifiers on a 1-in2 printed circuit board (PCB). The provided algorithm and code example uses a 2000™ microcontroller (MCU) LaunchPad™ Development Kit with the TMS320F28069M MCU for signal processing and angle calculation. The reference design uses an innovative, scattered-signal processing method. This method improves the system accuracy by 250% while maintaining hardware costs and complexity to a reasonable level. The TIDA-01527 is a low-cost companion design for the TIDA-00796 and TIDA-00363 reference designs. These designs are based on the PGA411-Q1 and offer advanced features such as protections and diagnostics.
Возможности:

±0.25° angle readout accuracy or ±0.1° using innovative scattering signal processing method Undersampling algorithm for angle calculation Industry standardized components Minimalist approach on 1-in2 four-layer PCB Example firmware for TMS320F28069M C2000™ MCU including source code
