Analog Devices LTM8024 | Demoboard DC1868A
40VIN, Dual 3.5A or Single 7A Silent Switcher μModule Regulator
Overview
| Topology | Buck Converter |
| Input voltage | 7-40 V |
| Switching frequency | 200-3000 kHz |
| Output 1 | 5 V / 3 A |
Description
The LTM8024 is 40VIN, dual 3.5A or single 7A step-down Silent Switcher µModule® regulator. The Silent Switcher architecture minimizes EMI while delivering high efficiency at frequencies up to 3MHz. Included in the package are the controllers, power switches, inductors, and support components. Operating over a wide input voltage range, the LTM8024 supports output voltages from 0.8V to 8V, and a switching frequency range of 200kHz to 3MHz, each set by a single resistor. Only the bulk input and output filter capacitors are needed to finish the design. The LTM8024 product video is available on website.The LTM8024 is packaged in a thermally enhanced, compact (9mm × 11.25mm × 3.32mm) over-molded ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8024 is RoHS compliant.
Features
- Two Complete Step-Down Switching Power Supplies
- Low Noise Silent Switcher® Architecture
