IC REG CHARGE PUMP INV DL 8UMAX

The MAX8653 dual-output, synchronous, step-down regulator contains low R DS(ON) integrated high-side MOSFET switches for ease of layout and achieving small footprints. Each output delivers up to 5A. The output voltage is adjustable down to 0.6V and operates from a 9V to 14V input voltage. The MAX8653 uses a proprietary high-bandwidth, constant-frequency, peak-voltage-mode control architecture and operates at an adjustable switching frequency between 300kHz to 1.5MHz. The architecture is suitable for use with a wide range of output capacitor technologies such as aluminum electrolytic, POSCAPs, and ceramic capacitors for flexible design. The simple compensation scheme achieves fast response under both line and load transients. The switching frequency is adjustable using a single external resistor. The output channels operate 180° out-of-phase to reduce the input ripple current, thus reducing the required input capacitance. The high operating frequency minimizes the size of external components. The external reference input (REFIN) enables implementation of tracking applications such as DDR power supplies. The MAX8653 utilizes internal digital soft-start and features a lossless (cyle-by-cyle) current sensing. It includes adjustable, hiccup-mode current-limit and short-circuit protection for minimum power dissipation under fault conditions. Each output contains an enable (EN_) input along with a power-good (POK_) signal for easy sequencing. The MAX8653 is available in a 28-pin, 5mm x 5mm thin QFN package.

The MAX8657/MAX8658/MAX8659 form a chipset for supporting the latest CPU power specifications, Intel® VRD10/VRD11, and AMD® K8/K8 Rev F, as well as a reference input for all other power-supply needs. The MAX8657/MAX8658 are master controllers with all the necessary control and housekeeping circuitry in addition to having integrated power MOSFETs for up to 25A/phase output. The MAX8659 is the slave with integrated MOSFETs for up to 25A/phase output, and has local control functions such as current loop, overtemperature protection, undervoltage lockout (UVLO), and OVP. The number of phases in operation is established by control pins on the slave, which are hardwired as high, low, or unconnected. The MAX8659 slave contains a PWM comparator, driver, integrated MOSFETs, and bootstrap diodes to support up to 25A of output current. The IC accepts control/clock signals from the MAX8657/MAX8658 master to regulate the output inductor current. Address bits on the MAX8659 enable the slaves to decode the clock signal appropriately to implement 2/3/4/5/6/7/8-phase operation. The MAX8657/MAX8658 incorporate a proprietary “rapid active average” current-mode control scheme for precise load sharing between phases as well as accurate droop-setting independent of inductor tolerances. Either parasitic inductor DCR or resistive current sensing is implemented. The MAX8657/MAX8658 are available in a 56-pin 8mm x 8mm thin QFN package. The MAX8659 is available in a 40-pin 6mm x 6mm thin QFN package. Learn More About PowerMind™ Applications Graphic Cards Power-Supply Modules Servers Telecom/Datacom Power Supplies Workstations
