Description

General part information

MAX8577 Series

The MAX8576–MAX8579 synchronous PWM buck controllers use a hysteretic voltage-mode control algorithm to achieve a fast transient response without requiring loop compensation. The MAX8576/MAX8577 contain an internal LDO regulator allowing the controllers to function from only one 3V to 28V input supply. The MAX8578/MAX8579 do not contain the internal LDO and require a separate supply to power the IC when the input supply is higher than 5.5V. The MAX8576–MAX8579 output voltages are adjustable from 0.6V to 0.9 x VINat loads up to 15A.Nominal switching frequency is programmable over the 200kHz to 500kHz range. High-side MOSFET sensing is used for adjustable hiccup current-limit and short-circuit protection. The MAX8576/MAX8578 can start up into a precharged output without pulling the output voltage down. The MAX8577/MAX8579 have startup output overvoltage protection (OVP), and will pull down a precharged output.ApplicationsAGP and PCI Express® Power SuppliesGraphic-Card Power SuppliesMotherboard Power SuppliesPoint-of-Load Power SuppliesSet-Top Boxes
