MAX8770GTL+

Special Purpose Regulators Overview

The MAX8770GTL+ is a switching controller designed for notebook CPU power supplies, manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates in a non-isolated buck topology with a single output capable of adjustable voltage up to 1.5 V. The device supports a maximum duty cycle of 100% and functions at a switching frequency of 600 kHz. It features a shutdown control input and draws a typical operating supply current of 5 mA at a 5 V supply voltage. The component is rated for an extended temperature range from -40°C to +105°C and is housed in a 40-lead TQFN surface-mount package.
