MAX17596Peak-Current-Mode Controllers for Flyback and Boost Regulators | DC DC Switching Controllers | 3 | Active | The MAX17595/MAX17596/MAX17597 is a family of peak-current-mode controllers for design of wide input-voltage flyback and boost regulators. The MAX17595 offers optimized input thresholds for universal input AC-DC converters and telecom DC-DC (36V to 72V input range) power supplies. The MAX17596/MAX17597 offer input thresholds suitable for low-voltage DC-DC applications (4.5V to 36V). The MAX17597 implements a boost converter. All three controllers contain a built-in gate driver for external n-channel MOSFETs.The MAX17595/MAX17596/MAX17597 house an internal error amplifier with 1% accurate reference, eliminating the need for an external reference. The switching frequency is programmable from 100kHz to 1MHz with an accuracy of 8%, allowing optimization of magnetic and filter components, resulting in compact and cost-effective power conversion. For EMI-sensitive applications, the MAX17595/MAX17596/MAX17597 family incorporates a programmable frequency dithering scheme, enabling low-EMI spread-spectrum operation.Users can start the power supply precisely at the desired input voltage, implement input overvoltage protection, and program soft-start time. A programmable slope compensation scheme is provided to ensuree stability of the peak-current-mode control scheme.Hiccup-mode overcurrent protection and thermal shutdown are provided to minimize dissipation in overcurrent and overtemperature fault conditions.ApplicationsBattery-Powered ApplicationsIndustrial and Telecom ApplicationsUniversal Input Offline AC-DC Power SuppliesWide-Range DC-Input Flyback/Boost Battery Chargers |

MAX17600.8A, Low-Noise, 1MHz, Step-Up DC-DC Converter | Development Boards, Kits, Programmers | 10 | Active | The MAX1760/MAX1760H are high-efficiency, low-noise, step-up DC-DC converters intended for use in battery-powered wireless applications. They combine low quiescent supply current (100µA) with a high 1MHz operating frequency. Small external components and tiny 10-pin TDFN and µMAX® packages make this device an excellent choice for small hand-held applications. The MAX1760 is activated by a logic-low active-low ON signal while the MAX1760H is activated by a logic-high ON input.Both devices use a synchronous-rectified pulse-width-modulation (PWM) boost topology to generate 2.5V to 5.5V outputs from a wide range of inputs, such as 1 to 3 alkaline or NiCd/NiMH cells or a single lithium-ion (Li+) cell. Proprietary Idle-Mode™ circuitry significantly improves light-load efficiency and smoothly transitions to fixed-frequency PWM operation at higher load currents.Low-noise, forced-PWM mode is available for applications requiring constant-frequency operation at all load currents. PWM operation can also be synchronized to an external clock to protect sensitive frequency bands in communications equipment. Analog soft-start and adjustable current limit permit optimization of efficiency, external component size, and output voltage ripple.ApplicationsDigital Cordless PhonesHandheld InstrumentsPalmtop ComputersPCS PhonesPersonal CommunicatorsTwo-Way PagingWireless Handsets |

MAX176014A Sink/Source Current, 12ns, Dual MOSFET Drivers | Evaluation and Demonstration Boards and Kits | 6 | Active | The MAX17600–MAX17605 devices are high-speed MOSFET drivers capable of sinking /sourcing 4A peak currents. The devices have various inverting and noninverting part options that provide greater flexibility in controlling the MOSFET. The devices have internal logic circuitry that prevents shoot-through during output-state changes. The logic inputs are protected against voltage spikes up to +14V, regardless of VDDvoltage. Propagation delay time is minimized and matched between the dual channels. The devices have very fast switching time, combined with short propagation delays (12ns typ), making them ideal for high-frequency circuits. The devices operate from a +4V to +14V single power supply and typically consume 1mA of supply current. The MAX17600/MAX17601 have standard TTL input logic levels, while the MAX17603 /MAX17604/MAX17605 have CMOS-like high-noise margin (HNM) input logic levels. The MAX17600/MAX17603 are dual inverting input drivers, the MAX17601/MAX17604 are dual noninverting input drivers, and the MAX17602/MAX17605 devices have one noninverting and one inverting input. These devices are provided with enable pins (ENA, ENB) for better control of driver operation.These devices are available in 8-pin (3mm x 3mm) TDFN, 8-pin (3mm x 5mm) µMAX®, and 8-pin SO packages and operate over the -40°C to +125°C temperature range.ApplicationsDC-DC ConvertersMotor ControlPower MOSFET SwitchingPower-Supply ModulesSwitch-Mode Power Supplies |
