The MAX1771EPA is a step-up switching controller from Analog Devices, offering high efficiency and low supply current. It provides 90% efficiency over a 30mA to 2A load and can deliver up to 24W of output power. The device features a current-limited pulse-frequency-modulation (PFM) control scheme, which combines the benefits of PWM converters with reduced supply current.
This controller supports an input voltage range of 2V to 16.5V and operates at a high switching frequency of up to 300kHz. The output voltage can be preset at 12V or adjusted using external resistors. It is designed to drive an external N-channel MOSFET switch.
The MAX1771EPA is available in an 8-DIP package and is suitable for through-hole mounting. It operates within an ambient temperature range of -40°C to 85°C. Key control features include an Enable function, and it has a maximum duty cycle of 92% and a switching frequency of 300kHz.
