LV5683P
Overview
For Car Audio Systems
Multi Voltage Regulator IC
The LV5683P is a multi voltage regulator suitable for USB silicon tuner car-audio systems. This IC has 4 outputs, VDD 5V(3.3V), AUDIO(8.5V), SWU(3.3V) and USB5V(CD 8V: available). About protection circuits, it has Over-current-protection, Over-voltage-protection and Thermal-shut-down. VCC1(SWU and USB supply) is independent terminal from VCC, and accepts lower voltage(ex. From DC/DC converter) which enables to reduce power dissipation.
Features
- 4 system regulator VDD(LCD micon) : VOUT 5.0V(3.3V), IO max 300mA, reverse current prevention. Audio : VOUT 8.5V, IO max 300mA SWU(systems) : VOUT 3.3V, IO max 500mA USB : VOUT 5.0V(8.0V available for CD), IO max 1100mA
- Over-current-protection
- Over-voltage-protection: Typ 21V(except VDD)
- Thermal-shut-down Typ 175ºC
- Applied Pch-LDMOS for output stages.
(Warning)The protector functions only improve the IC’s tolerance and they do not guarantee the safety of the IC if used under the conditions out of safety range or ratings. Use of the IC such as use under overcurrent protection range or thermal shut down state may degrade the IC’s reliability and eventually damage the...
