LTM8029IY#PBF

LTM®8029 is a 36VIN, 600mA step-down µModule® converter with 5µA quiescent current. It is an adjustable frequency buck switching regulator consumes only 5μA of quiescent current. The LTM8029 can accept input as high as 36VIN and operates at low input voltages due to its off-time skipping capability. Burst Mode operation maintains high efficiency at low output currents while keeping the output ripple low. The RUN pin features an accurate threshold and the shutdown current is 0.9μA. A power good flag signals when VOUT reaches 90% of the programmed output voltage. Application includes automotive battery regulation, power for portable products, distributed supply regulation, industrial supplies, wall transformer regulation.

• Maximum input voltage is 4.5V (TA=25°C, VIN=12V, RUN=2V)
• Output DC current range from 10 to 600mA (TA=25°C, VIN=12V, RUN=2V)
• Typical line regulation is 0.3% (5.5V <lt/> VIN <lt/> 36V, IOUT=600mA)
• Typical switching frequency is 2.2MHz (RT=41.2K, TA=25°C)
• Typical internal feedback resistor is 1Mohm (TA=25°C, VIN=12V, RUN=2V)
• Typical PGOOD leakage current is 0.1µA (PGOOD=6V, TA=25°C)
• Excellent dropout performance, can be used as an inverter
• Current mode control
• 35-lead BGA package
• Temperature range from -40°C to 125°C
