Other Parts Discussed in Thread: TPS54360, TPS54060A
Hello,
I'd like to use TI's LM5001 (Non-Automotive Version) for our IP PBX application.
Specification
- Vin: 48V
- Vout: -26V, -42V, -58V
- Iout: Max 0.7A (700mA)
1) Power Topologies
• Supply power to SLTC in PBX using CUK Or Inverter charge pump
2) TI Part
• Design of Negative Output and Multi port using LM5001
-. By changing the Buck Converter, the negative output state is created, and then the output voltage is synchronized to supply the load share and output with -11.6V, -23.2V, 34.8V, -46.4V, -58V.
• Competitors are: Linear LT3758
3) Competition PBX Reference Power rail
4) LM5001 concept (Previous developer received from TI BU.)
5) Questions
-. Charge pump & COUT Value
-. FB stage of OP input value & Compensation Value
-. 6 Winding design guide
thanks,
TS
