The MAX1771CSA is a step-up switching controller from Analog Devices, offering up to 90% efficiency across a 30mA to 2A load current range. This device is optimized for battery-powered applications, utilizing a unique current-limited pulse-frequency-modulation (PFM) control scheme that minimizes supply current to just 110µA maximum.
With a wide input voltage range of 2V to 16.5V, the MAX1771CSA can power loads up to 24W by driving an external N-channel MOSFET. Its high switching frequency of up to 300kHz allows for the use of miniature surface-mount magnetics. The output voltage is preset at 12V but can be adjusted using two external resistors.
Key features include a low 5µA maximum shutdown current and a 100mV current-limit threshold for optimized efficiency at low input voltages and noise reduction. Applications include positive LCD-bias generators, flash memory programmers, high-power RF power-amplifier supplies, and portable communication devices.
The MAX1771CSA is available in an 8-SOIC surface-mount package, suitable for compact designs. Its operating temperature range is 0°C to 70°C.
