Description
The TI Design TIDA-00200 proposes an interleaved flyback topology for battery charger applications that require an output power level of ~200W with a minimized bill of material. Besides the actual electronic components the efforts for cooling are a major contributor to the overall design cost. By taking advantage of the LM5032 High Voltage Dual Interleaved Current Mode Controller the design accomplishes great efficiency of 90% at full load and at the same time spreads out the heat for greatly reduced cooling efforts. A fan is typically not needed; the need for smaller form factor heat sinks provides additional design flexibility.
Features
• 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 Interleaved Current Mode Controller
• Programmable Line Under-Voltage Lockout & Cycle-by-cycle Current Limit
• Feedback based on TLC272 Dual Single Supply Operational Amplifier
