MAX8858Smallest, All-Internal MOSFET, 6-Channel DSC PMIC in a 5mm x 5mm TQFN | Integrated Circuits (ICs) | 2 | Unknown | The MAX8858 PMIC provides a complete power-supply solution for digital still cameras (DSCs) and digital video cameras (DVCs). The MAX8858 improves performance, component count, and board space utilization compared to currently available solutions for two AA cell and dual-battery designs. On-chip power MOSFETs provide up to 95% efficiency for critical power supplies. The CCD inverter can operate directly from two AA/NiMH batteries without the use of any additional external components.Step-up synchronous-rectified DC-DC converter (SU). The MAX8858 is bootstrapped from VVSU.MAIN synchronous-rectified step-up DC-DC converter (M) with active discharge for DSP I/O supply voltage.SDZ synchronous-rectified step-down DC-DC converter (SDZ) with active discharge for DSP DDR supply voltage.Low-voltage (down to 1V) synchronous-rectified step-down DC-DC converter (SD) with active discharge for DSP core supply voltage.High-voltage step-up DC-DC converter (CCDBST) for CCD imagers or positive LCD bias supplies.Transformerless inverting DC-DC converter (CCDINV) with active discharge for CCD imagers or negative LCD bias supplies.This converter can connect directly to two AA batteries.Individual ON_ inputs provide independent on/off control for the SU, CCDBST, and CCDINV converters, while dual-function inputs allow independent on/off control or power-up sequencing of the MAIN, SDZ, and SD converters.The MAX8858 is available in a 5mm x 5mm x 0.8mm, 32-pin thin QFN package and operates over the -40°C to +85°C extended temperature range.ApplicationsDSCs and DVCsPDAs and Portable Media Players |

MAX8864Low-Dropout, 120mA Linear Regulators | Integrated Circuits (ICs) | 3 | Active | The MAX8863T/S/R and MAX8864T/S/R low-dropout linear regulators operate from a +2.5V to +6.5V input range and deliver up to 120mA. A PMOS pass transistor allows the low, 80µA supply current to remain independent of load, making these devices ideal for battery-operated portable equipment such as cellular phones, cordless phones, and modems.The devices feature Dual Mode™operation: their output voltage is preset (at 3.15V for the T versions, 2.84V for the S versions, or 2.80V for the R versions) or can be adjusted with an external resistor divider. Other features include low-power shutdown, short-circuit protection, thermal shutdown protection, and reverse battery protection. The MAX8864 also includes an auto-discharge function, which actively discharges the output voltage to ground when the device is placed in shutdown mode. Both devices come in a miniature 5-pin SOT23 package.ApplicationsCellular TelephonesCordless TelephonesElectronic PlannersHand-Held InstrumentsModemsPalmtop ComputersPCMCIA CardsPCS Telephones |
