描述The TI Design TIDA-00200 proposes an interleaved flybacktopology for battery charger applications that require an output power level of~200W with a minimized bill of material. Besides the actual electronic componentsthe efforts for cooling are a major contributor to the overal design cost. Bytaking advantage of the LM5032 High Voltage Dual Interleaved Current ModeController the design accomplishes great efficiency of 90% at full load and atthe same time spreads out the heat for greatly reduced cooling efforts. A fanis typically not needed; the need for smaller form factor heat sinks providesadditional design flexibility.
特性• Input: 100V-120V +/- 10% AC 50/60Hz
• Output Voltage 21V (5 Li-Ion battery cells), up-to 9.5 A charge current
• 90% Efficiency
• Interleaved Flyback Topology based on LM5032 High Voltage Dual InterleavedCurrent Mode Controller
• Programmable Line Under-Voltage Lockout & Cycle-by-cycle Current Limit
• Feedback based on TLC272 Dual Single Supply Operational Amplifier
