1 / 28 page  LTM8051 1 Rev. 0 For more information www.analog.com TYPICAL APPLICATION FEATURES DESCRIPTION Quad 40VIN Silent Switcher μModule Regulator with Configurable 1.2A Output Array The LTM®8051 is quad 40VIN, 1.2A step-down Silent Switcher μModule® regulator. The Silent Switcher archi- tecture minimizes EMI while delivering high efficiency at frequencies up to 3MHz. Included in the package are the controllers, power switches, inductors, and support com- ponents. Operating over a wide input voltage range, the LTM8051 supports output voltages from 0.8V to 8V, and a switching frequency range of 300kHz to 3MHz, each set by a single resistor. Only the bulk input and output filter capacitors are needed to finish the design. The LTM8051 product video is available on website. The LTM8051 is packaged in a compact (6.25mm × 11.25mm × 2.22mm) over-molded Ball Grid Array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8051 is available with SnPb (BGA) or RoHS compliant. Configurable Output Array The LTM8051 outputs can be paralleled in an array for up to 4.8A capability. 1.2A 1.2A 1.2A 1.2A 2.4A 1.2A 1.2A 3.6A 1.2A 4.8A 1.8-5VOUT from 7-40VIN Quad Step-Down Converter APPLICATIONS n Four Complete Step-Down Switching Power Supplies n Low Noise Silent Switcher® Architecture n CISPR22 Class B Compliant n CISPR25 Class 5 Compliant n Wide Input Voltage Range: 3V to 40V n Wide Output Voltage Range: 0.8V to 8V n 1.2A Continuous Output Current per Channel at 12VIN, 3.3VOUT, TA = 85°C n 1.5A Continuous Output Current per Channel at 12VIN, 3.3VOUT, TA = 60°C n Multiphase or Multi-µModule Parallelable for Increased Output Current n Selectable Switching Frequency: 300kHz to 3MHz n Compact Package (6.25mm × 11.25mm × 2.22mm) Surface Mount BGA n Automated Test Equipment n Distributed Supply Regulation n Industrial Supplies n Medical Equipment All registered trademarks and trademarks are the property of their respective owners.
