DESCRIPTION:
The SCT61240 is a highly integrated power management IC (PMIC) optimized for automotive camera system. It integrates three high efficiency synchronous BUCK converters (HVBUCK1, LVBUCK2, LVBUCK3), and a high-PSRR low noise LDO with OV/UV monitoring on all outputs.VOUT1 is the output of BUCK1, which is powered from VIN (Power Over Coax) and can output 1.2A continuous current with the output voltage set to LDOOUT+300mV/500mV or fixed 3.3V.
VOUT2 is the output of BUCK2, which is powered from VOUT1 and can output 600mA continuous current with the output voltage fixed to 1.8V.
VOUT3 is the output of BUCK3, which is powered from VOUT1 and can output 1.2A continuous current with the output voltage set to 1.1V/1.2V/1.3V/1.5V through RSET PIN for different sensors.
LDOOUT is the output of LDO, which is powered from VOUT1 (need to connect LDOIN to VOUT1) and can output 300mA continuous current with the output voltage set to 2.7V/2.8V/2.9V/3.3V through RSET PIN for different sensors.
With a compact QFN2.5x3.5 package, the SCT61240 greatly reduces external components count and PCB space.
