Automotive Off-battery Dual-phase Boost Converter Reference Design
Details
| Topologie | Aufwärtswandler |
| Eingangsspannung | 6-20 V |
| Ausgang 1 | 12 V / 1.75 A |
| Ausgang 2 | 12 V / 1.75 A |
| IC-Revision | A |
Beschreibung
This reference design is a high power, wide input voltage range circuit that uses synchronous boost controllers in a dual-phase configuration outputting four (4) switchable 12-V rails that each can supply up to 2.5 A with diagnostic features; plus a dual synchronous buck that generates two high current, lower voltage rails.
Eigenschaften
- Wide input voltage range of 9V to 20V, support transient down to 6V and up to 36V
- Dual-phase high current synchronous boost controllers configuration with > 98% efficiency under typical operating conditions
- Dual high-current synchronous outputs: 5V, 3A nominal; 3.8V, 6.5A nominal
- Reverse battery protection with zero IQ smart diode controller
- Minimized AM radio band interference
Typische Anwendungen
- Voltage Conditioning Module
- Aftermarket Head Unit
