MAX15109中文资料高效、8A、电流模式同步整流降压型开关稳压器，带有VID控制数据手册ADI规格书

描述 Description

The MAX15109 high-efficiency, current-mode, synchronous step-down switching regulator with integrated power switches deliver up to 8A of output current. This regulator operates from 2.7V to 5.5V and provides four output voltages using two VID control inputs.
This IC utilizes a current-mode control architecture with a high gain transconductance error amplifier. The current-mode control architecture facilitates easy compensation design and ensures cycle-by-cycle current limit with fast response to line and load transients.
The low RDS(ON) integrated switches ensure high efficiency at heavy loads while minimizing critical inductance, making the layout design a much simpler task with respect to discrete solutions. The high switching frequency (1MHz), along with the PWM current-mode architecture allows for a compact, all ceramic capacitor design.
The IC features a capacitor-programmable slew-rate control to reduce input current at the startup and when the output changes state under VID control. Internal control circuitry ensures safe-startup into a prebiased output. Power sequencing is controlled with the enable input and power-good output.
The IC is available in a 20-bump (4 x 5 array), 2.5mm x 2mm, WLP package and is fully specified over the -40°C to +85°C temperature range.
