MAXIM INTEGRATED / ANALOG DEVICES MAX1830EEE High-Efficiency Step-Down Regulator

The MAX1830EEE+ is a low-voltage, high-efficiency step-down (buck) regulator with synchronous rectification integrated within a 16-pin QSOP package. Designed for converting 3V to 5.5V input voltages down to low voltages, it is suitable for powering chipset supplies, CPU I/O, notebooks, and subnotebooks. This device features internal PMOS and NMOS switches, with resistance ratings optimized for efficient operation. It provides preset output voltages of +2.5V, +1.8V, or +1.5V, or an adjustable output from +1.1V to VIN, supporting continuous output currents up to 3A. It employs a current mode, constant off-time PWM control scheme with Idle Mode, ensuring high efficiency during light loads. Features include a programmable switching frequency up to 1MHz, digital soft-start, low power shutdown mode reducing supply current below 1µA, thermal shutdown, output short circuit protection, inrush current limiting, and no external Schottky diode is required. Operating over -40°C to 85°C with an accuracy of ±1.5% and efficiency up to 94%, it is ideal for portable power management and power conversion in compact electronics.
