MAX5035AUSA+

The MAX5035AUSA+ is a 1A, 76V, high efficiency MAXPower step-down DC-DC converter in 8 pin NSOIC package. This DC-DC converter operates from a 7.5V to 76V input voltage range. A unique voltage-mode control scheme with voltage feed-forward and an internal switching DMOSFET provides high efficiency over a wide input voltage range. This pulse width modulated converter operates at a fixed 125KHz switching frequency. The device also features automatic pulse-skipping mode to provide low quiescent current and high efficiency at light loads. Under no load, it consumes only 270µA and in shutdown mode, consumes only 10µA. The IC also features undervoltage lockout, cycle-by-cycle current limit, hiccup mode output short circuit protection and thermal shutdown. The device uses an internal low on-resistance, high voltage, DMOS transistor to obtain high efficiency and reduce overall system cost.
