MAX8576, MAX8577, MAX8578, MAX8579 3V To 28V Input, Low-Cost, Hysteretic Synchronous Step-Down Controllers

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 VIN at 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.
