The device can generate output voltages as low as 0.6V, enabling it to power the latest generation of low voltage DSPs and microcontrollers. It utilises 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 compact solution footprint.
LTC3564 uses internal switches with an RDS(ON) of only 0.15Ohm (N-Channel and P-Channel) to deliver efficiencies as high as 96 per cent. It also has low dropout 100 per cent duty cycle operation to extend battery run-time. LTC3564 utilises automatic Burst Mode operation to achieve only 20uA of no load quiescent current and less than 1uA in shutdown. Other features include ±2 per cent output voltage accuracy, current mode operation and over-temperature protection.
LTC3564EDBC is available in a 2mmx3mm DFN-6 package, while LTC3564ES5 is available in a 5-lead ThinSOT package. Both versions are available from stock. Pricing starts at $1.95 each for both parts in 1,000-piece quantities. LTC3564IDBC and LTC3564ISS are both tested and guaranteed to operate from a -40°C to 125°C junction temperature. They are both priced at $2.24 in 1,000-piece quantities and are available from stock. |
