The switching frequency (200kHz to 1MHz), external compensation network, and current limit can also be adjusted to optimize designs in terms of space, performance, and cost. This combination of versatility and performance makes the MAX15023 suitable for a variety of high-reliability applications such as telecom, networking, storage, and server equipment.
The MAX15023 uses cycle-by-cycle lossless current sensing to reduce power loss and eliminate the need for an external sense resistor. Additionally, the device’s adaptive synchronization eliminates external freewheeling Schottky diodes. Other features include the ability to start up monotonically when the output has a prebiased voltage; proprietary, adaptive digital soft-start for controlled turn-on; and two independent enable inputs and two independent power-good indicators with precise turn-on/turn-off thresholds, which can be used for supply monitoring and power sequencing.
