LTC3630IMSE#PBF

LTC3630 is a high efficiency step-down DC/DC converter with internal high side and synchronous power switches that draws only 12μA typical DC supply current while maintaining a regulated output voltage at no load. It can supply up to 500mA load current and features a programmable peak current limit that provides a simple method for optimizing efficiency and for reducing output ripple and component size. This combination of Burst Mode® operation, integrated power switches, low quiescent current, and programmable peak current limit provides high efficiency over a broad range of load currents. Additionally, this includes a precise run threshold and soft-start feature to guarantee that the power system start-up is well-controlled in any environment. Typical applications are industrial control supplies, medical devices, distributed power systems, portable instruments, battery-operated devices, automotive, avionics.

• Robust converter suited for regulating a wide variety of power sources
• Feedback comparator output enables multiple this to be paralleled in higher current applications
• Synchronous operation for highest efficiency
• Internal high side and low side power MOSFETs, no compensation required
• Low dropout operation is 100% duty cycle
• Low quiescent current is 12µA, wide output range is 0.8V to VIN
• 0.8V ±1% feedback voltage reference, precise RUN pin threshold
• Internal and external soft-start, few external components required
• 16-lead plastic MSOP package
• Temperature range from –40°C to 125°C
