design ideas High Efficiency 17V, 2A Synchronous Monolithic
Step-Down Regulator with Ultralow Quiescent Current
in a 3mm Г— 3mm DFN
Gina Le and Jian Li Portable power electronic devices require compact power supplies that can deliver
high efficiency over wide input and output voltage ranges. Other requirements include
low standby current, low dropout operation, output voltage accuracy and a fast loop
response to line and load transient. The LTC3624 is a 17V, 2A synchronous monolithic
step-down regulator, featuring ultralow quiescent current and high efficiency over a
wide VIN and VOUT rangeвЂ”an excellent choice for battery powered equipment, portable
instrumentation, emergency radios and general purpose step-down power supplies.
Some of the LTC3624вЂ™s notable features: Wide VIN range: 2.7V to 17V Wide VOUT range: 0.6V up to VIN at 2A
rated output current 95% peak efficiency Constant frequency of 1MHz or 2.25MHz Ultralow quiescent current of 3.5Вµ A Low dropout operation at high duty
cycle Current mode architecture, allowing
excellent line and load transient
response.
Despite its small size, the LTC3624 remains
flexible, enabling designers to optimize VIN
2.7V TO 17V solutions by simply selecting a desired
mode or frequency of operation. A userselectable mode input is provided with the
following options: Burst Mode operation
provides the highest efficiency at light
loads, while pulse-skipping mode provides
the lowest output voltage ripple. Forced …
