Product Overview
LTC®3638 is a high efficiency step-down DC/DC regulator with internal power switch that draws only 12µA typical DC supply current while maintaining a regulated output voltage at no load. This can supply up to 250mA 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. Its combination of Burst Mode® operation, integrated power switch, 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, avionics, automotive.
- Wide operating input voltage range from 4V to 140V, internal low resistance power MOSFET
- No compensation required, low dropout operation is 100% duty cycle
- Low quiescent current is 12µA, wide output range from 0.8V to VIN
- 0.8V ±1% feedback voltage reference, precise RUN pin threshold
- Internal or external soft-start, few external components required
- Programmable input overvoltage lockout
- Feedback pin current is 10nA maximum (VFB=1V, VPRG1=VPRG2=0V)
- VIN undervoltage lockout range from 3.5 to 4V (VIN rising, TA=25°C. VIN=12V)
- 16-lead plastic MSOP package
- Temperature rating range from -40°C to 150°C
