MAXIM INTEGRATED / ANALOG DEVICES MAX8505EEET High-Efficiency Step-Down Regulator
The MAX8505EEE+T is a highly accurate, 1% precise internal switch-mode step-down regulator housed in a 16-pin QSOP package. It operates with an input voltage range of 2.6V to 5.5V and provides an adjustable output voltage from 0.8V to approximately 0.85 times the input voltage, capable of delivering up to 3A of current. The device supports input voltages as low as 2.25V when powered with a 2.6V to 5.5V bias supply. Integrated with power MOSFETs, it switches at frequencies of 1MHz or 500kHz, enabling compact designs. Its current mode PWM control simplifies compensation with ceramic or polymer output capacitors and ensures excellent transient response. During startup, the regulated output ramps up gradually to prevent voltage dips, supporting reliable power delivery for microprocessors, ASICs, DSPs, FPGA cores, chipset supplies, servers, storage systems, and telecommunications equipment. The regulator includes features such as current limit, short circuit protection, thermal overload protection, and a rugged design. It operates across a wide temperature range from -40°C to 85°C. Its compact size is achieved with a 9mm x 6mm footprint, requiring a 1µH inductor and a 47µF ceramic capacitor. The soft-start can be externally adjusted with a capacitor. It supports ceramic or polymer output capacitors, maintains ±1% output accuracy over various loads, line, and temperature conditions, and provides fast transient response. An in-regulation soft-start limits output voltage dips during power-up, and an open-drain Power-OK (POK) monitor indicates the output voltage status. Typical supply current consumption is 6mA at 3.3V input and 10mA at 5.5V input, over the temperature range.
