The LV5684PVD is a power supply IC suitable for USB/CD receiver system for car audio system.
This IC integrates 5 systems of regulator output, 2 systems of high side power switch, overcurrent protector,
overvoltage protector and overheat protector
Supply for VDD and SW33V outputs is low voltage specification, which enables drastic reduction of power dissipation
compared to the existing model. (the package is HZIP15).

Supply input
V6IN: 6V for VDD, system (SW33V)
VCC1: For internal reference voltage, control circuits
In case of voltage drop of V6IN, VCC1 supplies to VDD output.
VCC2: For AUDIO, illumination, CD, EXT/ANT
•
Overcurrent protector
•
Overvoltage protector(OVP): VCC1,VCC2 Typ 23V (All outputs except VDD are turned off)
Overvoltage shutdown(OVS): V6IN Typ 23V (All outputs except VDD are turned off)
•
Overheat protector: Typ 175°C
•
PchLDMOS is used in power output block
(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, thermal shutdown state or V6IN
OVS condition may degrade the IC’s reliability and eventually damage the IC.

*V6IN is designed to tolerant toward short period of
over-voltage (max 20V) which is assumed in condition of short
circuit between VCC1/VCC2 and V6IN.
However, applying over-voltage higher than maximum rating
(7V) to V6IN may degrade the device reliability

*1 : All the specification is defined based on the tests performed under the conditions where Tj and Ta (= 25°C) are almost equal. These tests were performed
with pulse load to minimize the increase of junction temperature (Tj).
(*1) Make sure that output capacitors are greater than 10uF and meets the condition of ESR = 0.001 to 10Ω , in which voltage/ temperature dependence and
unit differences are taken into consideration. Moreover, in case of electrolytic capacitor, high-frequency characteristics should be sufficiently good.
