Exar PowerBlox buck regulators feature extremely high current densities.
The typical price in volume is GBP 1.80 to GBP 2 each.
The nonisolated regulators measure 11.5 x 7.5 x 10.2mm, operate from 4.75 to 28V DC input and are available in seven standard versions with output voltages from +1.8 to +12V DC.
Devices with any output voltage from +1.5 to +12V DC can be supplied to special order.
Output current for all types is 0.5A and the regulators feature integral short circuit protections and thermal shutdown.
Typical ripple and noise is 30 to 50mV, depending on output voltage.
This can be halved where necessary with the addition of a 100uF capacitor on the output.
Otherwise, no external components are needed with these devices which have a maximum operating temperature of +85C.
These regulators are commonly used to increase the input voltage range at the input of isolated DC/DC convertors or to provide improved loading and regulation at the output of such convertors.
Standard-output versions are available from stock.
