MAX1519, MAX1545 Dual-Phase, Quick-PWM Controllers For Programmable CPU Core Power Supplies

The MAX1519 MAX1545 are dual-phase, Quick-PWM", Step-down controllers for desktop and mobile Pentium 4 (P4) CPU core supplies. Dual-phase operation reduces input ripple current requirements and output voltage ripple while easing component selection and layout difficulties. The Quick-PWM control scheme provides instantaneous response to fast load-current steps. The MAX1519 MAX1545 include active voltage positioning with adjustable gain and offset, reducing power dissipation and bulk output capacitance requirements.
The MAX1519 MAX1545 are intended for two different notebook CPU core applications: stepping down the battery directly or stepping down the 5V system supply to create the core voltage. The single-stage conversion method allows these devices to directly step down High-Voltage batteries for the highest possible efficiency. Alternatively, two-stage conversion (stepping down the 5V system supply instead of the battery) at a higher switching frequency provides the minimum possible physical size.
The MAX1519 MAX1545 comply with Intel's P4 specifications. The Switching Regulator features soft-start, power-up sequencing, and soft-shutdown. The MAX1519 MAX1545 also feature independent four-level Logic inputs for setting the suspend voltage (S0-S1).
The MAX1519 MAX1545 include output undervoltage protection (UVP), thermal protection, and voltage Regulator power-OK (VROK) output. When any of these protection features detect a fault, the controller shuts down. Additionally, the MAX1519 MAX1545 include overvoltage protection.
The MAX1519 MAX1545 are available in low-profile, 40-pin, 6mm x 6mm thin QFN packages. For other CPU platforms, refer to the pin-to-pin compatible MAX1544 and MAX1532/MAX1546/MAX1547 data sheets.
