MAX5067ETH中文资料Dual-Phase, +0.6V to +3.3V Output Parallelable, Average-Current-Mode Controllers数据手册ADI规格书

描述 Description

General Description
The MAX5065/MAX5067 dual-phase, PWM controllers provide high-output-current capability in a compact package with a minimum number of external components. The MAX5065/MAX5067 utilize a dual-phase, average-current-mode control that enables optimal use of low RDS(ON) MOSFETs, eliminating the need for external heatsinks even when delivering high output currents.
Differential sensing enables accurate control of the output voltage, while adaptive voltage positioning provides optimum transient response. An internal regulator enables operation with input voltage ranges of +4.75V to +5.5V or +8V to +28V. The high switching frequency, up to 500kHz per phase, and dual-phase operation allow the use of low-output inductor values and input capacitor values. This accommodates the use of PC board embedded planar magnetics achieving superior reliability, current sharing, thermal management, compact size, and low system cost.
