Dual-Output, 6A, 3MHz, 2.7V to 16V, MAX20812/MAX20812T Step-Down Switching Regulator Memory V DDQ General Description I/O Pins of an FPGA/DSP/MCU The MAX20812/MAX20812T are dual-output, fully Benefits and Features integrated, highly efficient, step-down DC-DC switching regulators. These regulators are able to operate from High Power Density with Low Component Count 2.7V to 16V input supplies, and each output can be Dual-Output or Dual-Phase Operation regulated from 0.5V to 5.8V, delivering up to 6A of load Single-Supply Operation with Integrated LDO for current per output. With the MAX20812, the two outputs Bias Generation can be connected in parallel as a single-output, dual- Optional 2.5V to 5.5V External Bias for Higher phase regulator that supports up to 12A load current. Efficiency Compact 3.5mm x 4.6mm, 21-Pin, FC2QFN The switching frequency of this device can be configured Package from 500kHz to 3.0MHz and provides the capability of Internal Compensation optimizing the design in terms of solution size and Wide Operating Range performance. 2.7V to 16V Input Voltage Range The MAX20812/MAX20812T utilize fixed-frequency, 0.5V to 5.8V Output Voltage Range current-mode control with internal compensation. The 500kHz to 3MHz Configurable Switching dual-switching regulators operate 180 out-of-phase. Frequency The MAX20812/MAX20812T feature a selectable -40C to +125C Junction Temperature Range advanced modulation scheme (AMS) to provide Three Pin-Strap Programming Pins to Select improved dynamic load transient performance. The Different Configurations devices also feature selectable discontinuous current Independent Enable and Power Good for Each mode (DCM) operation to improve light load efficiency. Output Operation settings and configurable features can be Optimized Performance and Efficiency selected by connecting pin-strap resistors from the 92.5% Peak Efficiency with V = 12V, DDH PGM pins to ground. V = 1.8V, and f = 1MHz OUT SW The MAX20812/MAX20812T have an internal 1.8V LDO Interleaved 180 Out-of-Phase Operation output to power the gate drives (V ) and internal CC Selectable AMS to Improve Load Transient circuitry (AVDD). The devices also have an optional LDO Selectable DCM to Improve Light Load Efficiency input pin (LDOIN), allowing connection from a 2.5V to Active Current Balancing for Dual-Phase 5.5V bias input supply for optimized efficiency. Operation (MAX20812 only) The MAX20812/MAX20812T integrate multiple CURRENT protections including positive and negative overcurrent RATING* INPUT OUTPUT protection, output overvoltage protection, and DESCRIPTION (DUAL- VOLTAGE VOLTAGE overtemperature protection to ensure a robust design.
