Linear Technology’s new LTC3606BEDD#PBF. LTC3606BEDD#PBF. is a 2.25MHz, synchronous buck regulator with programmable average input current limit. According to the company it can deliver up to 800mA of continuous output current with efficiencies as high as 96%. Using a constant frequency and current mode architecture, the LTC3606BEDD#PBF. LTC3606BEDD#PBF. operates from an input voltage range of 2.5V to 5.5V, making it particularly suitable for single-cell Li-Ion and USB applications. It can generate output voltages as low as 0.6V, enabling it to power the latest generation of low voltage DSPs and microcontrollers. The LTC3606B uses a switching frequency of 2.25MHz, allowing the use of small, low cost ceramic capacitors and inductors less than 1 mm in height. The combination of high switching frequency, tiny externals and a 3mm x 3mm DFN package make the LTC3606B a compact synchronous step-down solution.
The LTC3606BEDD#PBF. LTC3606BEDD#PBF. is available from stock in a 3mm x 3mm DFN-8. Pricing starts at $2.10 each for 1,000-piece quantities. An industrial grade version, the LTC3606BIDD, is tested and guaranteed to operate over a -40°C to 125°C operating junction temperature range and is priced at $2.47 each in 1,000-piece quantities.
