Universal input reference design for 12-V lead acid battery charger
Details
| Topologie | Sperrwandler |
| Eingangsspannung | 85-265 V |
| Schaltfrequenz | 0.88-94 kHz |
| Ausgang 1 | 14 V / 2.5 A |
| IC-Revision | A |
Beschreibung
This reference design takes a Universal AC input (85 VAC - 265 VAC) and converts to a 17.5-V isolated output using a PSR flyback topology. It is then followed by a battery charger circuit, which outputs up to 15 V to a lead acid battery. This is a fast-charge design capable of delivering 12 V @ 2.5 A (30 W) to the battery.
Eigenschaften
- Universal input (85 VAC - 265 VAC), which can be used to power up the charger worldwide
- Conducted EMI testing provided
- Primary side regulated (PSR) flyback topology provides a cost-effective solution
- Small form factor to fit any mechanical housing of typical battery chargers
Typische Anwendungen
- Low Power AC to DC SMPS
- USB Type-C AC Adapters for Consumer Electronics
- Industrial and Medical SMPS
- Adapters and Chargers for Phones and Tablets
