ADI LTM4653EY#PBF

Неизолированный модуль PoL3.1V58V0.5 ~ 54.5V4A

Overview

Power by Linear / Analog Devices’ LTM4653EY#PBF is a 58 V, 4 A DC/DC step-down μModule regulator. These ultra-low noise devices are designed to meet the radiated emissions requirements of EN55022. Conducted emission requirements can be met by adding standard filter components. Included in the package are the switching controller, power MOSFETs, inductor, filters, and support components.Operating over an input voltage range of 3.1 V to 58 V, the LTM4653EY#PBF supports an output voltage range of 0.5 V to 94% of VIN, and a switching frequency range of 250 kHz to 3 MHz (400 kHz default), each set by a single resistor. For high load currents, the LTM4653EY#PBF can be paralleled in PolyPhase® operation and synchronized to an external clock. Only the bulk input and output filter capacitors are needed to finish the design. This regulator comes in a BGA package with an operating temperature range of -40°C to +125°C. The LTM4653EY#PBF is ideal for avionics, telecom, and RF systems.Features: Low EMI switch mode power supply, EN55022 class B compliant, Wide input voltage range: 3.1 V to 58 V, Up to 4 A output current, Output voltage range: 0.5 V ≤ VOUT ≤ 0.94 • VIN, ±1.67% total DC output voltage error over line, load, and temperature (-40°C to +125°C), Parallel and current share with multiple LTM4653s, Analog output current indicator, Programmable input voltage limiting, Constant-frequency current mode control, Power good indicator and programmable soft-start, Overcurrent, overvoltage, and overtemperature protection, BGA package, Temperature range: -40°C to +125°C, Avionics, Telecom, Network power supplies, RF systems, Video, imaging, and instrumentation, Automatic test and measurement (ATE)
