It can generate output voltages as low as 0.6V, enabling it to power the latest generation of low voltage DSPs and microcontrollers. It utilizes a constant 2.25MHz switching frequency, enabling the use of tiny, low cost ceramic capacitors and inductors less than a 1mm in height, providing a very compact solution footprint.
The LTC3564 uses internal switches with an RDS(ON) of only 0.15Ohm (N-Channel and P-Channel) to deliver efficiencies as high as 96%. It also has low dropout 100% duty cycle operation to extend battery run-time. The LTC3564 utilizes automatic Burst Mode™ operation to achieve only 20uA of no load quiescent current and less than 1uA in shutdown. Other features include ±2% output voltage accuracy, current mode operation and over-temperature protection.
