LT8601JUJ#PBF

LT®8601 is a triple channel, current mode, monolithic buck switching regulator with a programmable power-on reset. This can be configured for micropower burst mode or pulse-skipping operation at light load. Micropower operation results in quiescent current of 30µA with all three regulators operating as shown in the application below with no load applied. This uses a 2-phase clock with channel 1 operating 180° from channels 2 and 3 to reduce input ripple current on both HV and LV inputs. All channels have cycle-by-cycle current limit, providing protection against shorted outputs. Thermal shutdown provides additional protection. Typical applications are automotive systems, distributed supply regulation, industrial controls and power supplies.

• Flexible power supply system providing three outputs over a wide input voltage range
• Programmable power-on reset, power good indicators, 2-phase clock reduces input current ripple
• Minimum operating voltage is 2.7V typ (TA=25°C. VIN=PVIN1=PVIN2=12V, EN/UVLO=3V, PVIN3=3.3V)
• VIN quiescent current, shutdown is 1µA maximum (EN/UVLO=0.4V)
• Switching frequency range from 1.75 to 2.2MHz (RT=28.7K, TA=25°C. VIN=PVIN1=PVIN2=12V, EN/UVLO=3V)
• SYNC input current range -100 to 100nA
• 40-lead plastic QFN package
• Temperature rating range from -40°C to 150°C
