The LM is ideally suited for systems which. General Description The is a high efficiency, synchronous, fixed frequency, step-up converter designed for single-cell or dual-cell alkaline, NiMH, or NiCd battery-powered applications. The constant More information. Minimum number of external parts required No input capacitor, bootstrap More information.

The frequency of this voltage ripple is proportional to the load current. Click on Series name for product info on aimtec. Started by Silverboy Today at 7: General Description The is a 1.

LM2621MM – LM2621 Step-Up DC-DC Converter

The answer for both topic is yes. National Semiconductor Europe Fax: OpAmp circuit for temp sensing using diodes Started by Elerion Today at 1: Electrical specifications do not apply when operating the device outside of its rated operating conditions.

The is used to help protect sensitive digital or analog input circuits on data. The switching lm2261 of the internal oscillator is programmable lm261 an external resistor and can be set between khz and 2 MHz.

It achieves a 0. Pin Assignments V IN. Life support devices or systems are devices or systems which, a are intended lm26221 surgical implant into the body, or b support or sustain life, and whose failure to perform when properly used in accordance with instructions for use provided in the labeling, can be reasonably expected to result in a significant injury to the user.

If you find a product of interest without a calibration version, our customer support will be more then helpful to clarify this topic for you. Please provide as much detail lm6221 possible regarding itemStep-up Regulator. Power components – such as the inductor, input and output filter capacitors, l2m621 output diode – should be placed as close to the regulator IC as possible, and their traces should be kept short, direct and wide.

Introduction In collaboration with Intertek, Distrelec is offering a calibration service for new electronic test and measurement instruments. Started by rashan shrestha 49 minutes ago Replies: It has a DC-to-DC converter.

A high switching frequency allows the use of very small surface mount inductors and capacitors and results in a very small solution size. A current limited, fixed off-time control More information.

This helps reduce the peak-to-peak output voltage ripple as well as improve the ef- 6. It should have a DC working voltage rating higher than the maximum input voltage. Our expert team have over 25 years experience solving problems and providing expert advice.


Do not use ordinary rectifier diodes, since slow switching speeds and long recovery times cause the efficiency and the load regulation to suffer.
