MAX7771110V Input, Quad-Phase Configurable, 3A/Phase, High-Efficiency Buck Converter | Special Purpose Regulators | 8 | Active | The MAX77511/MAX77711 are four-phase, 3A/phase, configurable single to quad output, step-down buck regulators for 1s/2s Li+ battery inputs. Output voltage is programmable through an I2C interface between 0.25V and 5.2V. The buck has four combinable 3A switching phases (Φ) for up to four regulated outputs. Phases are configurable to higher-current multiphase outputs: 4Φ, (3+1)Φ, (2+2)Φ, (2+1+1)Φ, or (1+1+1+1)Φ.Six GPIOs can be purposed for I/O expansion or buck status and control. Pseudo-random spread-spectrum modulation suppresses EMI. Soft-start, soft-stop, and DVS slew times are programmable with I2C. MAX77711 offers a 300mA linear regulator.MAX77511/MAX77711 are available in a 64-bump, 3.54mm x 3.54mm wafer-level package (WLP).ApplicationsDSLR, Mirrorless, HD Video, and Action Cameras2-Cell Li+/Li-ion EquipmentNotebook Computers and RobotsEmbedded Microprocessors, FPGAs, or ASICs |

MAX77720Wide Output-Voltage Range, Dual-Polarity PMIC | Voltage Regulators - DC DC Switching Regulators | 2 | Active | The MAX77720 dual-output DC-DC converter generates two independently regulating positive and negative supply voltages. The positive output delivers up to 4W of power at the output while the negative output delivers up to 4.8W of power. The MAX77720 is ideal for powering time of flight (ToF) imaging sensors and OLED displays in smart internet of things (IoT) devices.The MAX77720 generates an adjustable negative output down to -24V and a positive output voltage up to +20V. The negative output operates at a fixed 1.5MHz frequency while the positive output operates at a fixed 1MHz frequency to ease noise filtering in sensitive applications and to reduce external component size.The nERR pin, when connected to an external device’s output pin, is used to disable the regulators to signal an external error. This error can be cleared through I2C from a host processor to re-enable the regulators. While in the error on state, there is an option for the active discharge to be enabled or disabled (for example, to set the regulator outputs to a high-Z floating).A bidirectional I2C serial interface allows for configuring and checking the status of the devices. Numerous factory-programmable options allow the device to be tailored for many applications, enabling faster time to market.APPLICATIONSToF SensorsOLED DisplaysBipolar Amplifiers |
MAX77734Ultra-Low Power Tiny PMIC with Power Path Charger for Small Li+ and 150mA LDO | Evaluation and Demonstration Boards and Kits | 6 | Active | The MAX77734 is a tiny PMIC for applications where size and simplicity are critical. The IC integrates a linear-mode Li+ battery charger, low-dropout linear regulator (LDO), analog multiplexer, and dual-channel current sink driver.The charger is designed for small-battery systems that require accurate termination as low as 0.375mA. The circuit can instantly regulate the system voltage when an input source is connected even if the battery is depleted.The 150mA LDO's output is programmable between 0.8V and 3.975V with I²C. The analog MUX enables an external ADC to perform conversions on battery V&I signals for power monitoring. The current sinks are capable of sinking 12.8mA each and can be programmed for LEDs to blink in custom patterns.The MAX77734 is available in a 20-bump, 0.4mm pitch wafer-level package (WLP).Design Solution: Can You Hear Me Now?

MAX777513.15A USB Type-C Autonomous Charger for 1-Cell Li+ Batteries | Evaluation and Demonstration Boards and Kits | 18 | Active | The MAX77751 is a standalone, 3.15A charger with integrated USB Type-C®CC detection and reverse boost capability. The fast-charge current and top-off current thresholds are easily configured with resistors. The MAX77751 operates with an input voltage of 4.5V to 13.7V and has a maximum input current limit of 3A. The IC also implements the adaptive input current limit (AICL) function that regulates the input voltage by reducing input current, to prevent the voltage of a weak adapter from collapsing or folding back.The USB Type-C Configuration Channel (CC) detection pins on the MAX77751 enable automatic USB Type-C power source detection and input current limit configuration. To support a variety of legacy USB as well as proprietary adapters, the IC also integrates BC1.2 detection using the D+ and D- pins. The IC runs the CC detection and BC1.2 detection automatically without any software as soon as the USB plug is inserted.The IC also offers Reverse-Boost capability up to 5.1V, 1.5A, which can be enabled with the ENBST pin. The STAT pin indicates charging status, while the INOKB pin indicates valid input voltage. Charging can be stopped by pulling the ITOPOFF pin low.The MAX77751 is equipped with a Smart Power Selector™ and a battery true-disconnect FET to control the charging and discharging of the battery or isolate the battery in case of a fault. The MAX77751 is offered in several variants to support Li-ion batteries with various termination voltages from 4.1V to 4.5V. The IC comes in a 3mm x 3mm, 0.4mm pitch 24-lead FC2QFN package making it suitable for low-cost PCB assembly.ApplicationsMobile Point-of-Sale (mPOS) TerminalsPortable Medical DevicesWireless HeadphonesGPS TrackersCharging Cradles for Wearable DevicesPower BanksMobile Routers |
