MAX1858A规格书详情
General Description
The MAX1858A/MAX1875A/MAX1876A dual, synchronized, step-down controllers generate two outputs from input supplies ranging from 4.5V to 23V. Each output is adjustable from sub-1V to 18V and supports loads of 10A or higher. Input voltage ripple and total RMS input ripple current are reduced by synchronized 180° out-of-phase operation.
Features
♦ 4.5V to 23V Input Supply Range
♦ 0 to 18V Output Voltage Range (Up to 10A)
♦ Adjustable Lossless Foldback Current Limit
♦ Adjustable 100kHz to 600kHz Switching Frequency
♦ Optional Synchronization
♦ Clock Output for Master/Slave Synchronization
♦ 4 x 90° Out-of-Phase Step-Down Converters (Using Two Controllers, Figure 7)
♦ Prebias Startup (MAX1875A/MAX1876A)
♦ Power Sequencing (MAX1858A)
♦ RST Output with 140ms Minimum Delay (MAX1858A/MAX1876A)
♦ Fixed-Frequency Pulse-Width Modulation (PWM) Operation
