New product: 12V, 2.2A Step-Down Voltage Regulator D24V22F12
We are pleased to introduce our new 12 V, 2.2 A switching regulator, the inaugural member of the D24V22Fx family of step down voltage regulators. We expect to release other voltage versions next month, but we wanted to get a 12 V version out right away since we did not offer a 12 V buck regulator that could do more than 1 A. The compact regulator works with input voltages up to 36 V and can typically deliver up to a continuous 2.2 A. It offers integrated reverse voltage protection along with over-current and over-temperature shutoff, and a power-good output can be used to determine when the regulator cannot maintain its output voltage.
Unlike linear regulators which waste a lot of power and generate a lot of heat in the process, this new regulator is very efficient, which means you can get the most out of your battery life:
Until we release other voltage versions of the D24V22Fx, the closest substitutes are the similar D24V25Fx family of step-down voltage regulators:
These regulators are the same size as the D24V22F12 and they have similar current capabilities and input voltage ranges, but they do not have the same pinout and they are based on a different internal design, so there are fundamental differences in operation.
See the D24V22F12 product page for more information on this new regulator, or visit our voltage regulator category to see all of our regulator options.
Is there a data sheet on your step down regulators? (D24V22Fx)
How does the Power Good terminal work? What state is it in when Enable is not active, and power is applied to the input and not applied to the input? (Does it signal power good regardless of the Enable terminal being enabled?)
I need a regulator that lets me know if the power is good before my processor signals the regulator to output...
Thanks a lot.
We do not release the name of the chip used on those regulators. The power good pin is an indicator of whether the output of the regulator is above 85% or 90% (depending on if the output voltage is falling or rising) of the intended output voltage. The power good pin is pulled low when the regulator is not enabled. It seems like you are looking for a feature that tells you if the input power is good, in which case this regulator is not appropriate.
