MAX5096 - (MAX5096 / MAX5097) Buck Converters

General Description

The MAX5096/MAX5097 easy-to-use, Dual Mode™, DC-DC converters operate as LDO (low dropout) or switch-mode buck converters.

At a high output load, the converters operate as high-efficiency pulse-widthmodulated (PWM) switch-mode converters and reduce the power dissipation.

Key Features

  • include a power-on reset output with a capacitor-adjustable timeout period, programmable soft-start, output tracking, output overload, short-circuit and thermal shutdown protections. The MAX5096/MAX5097 operate over the -40°C to +125°C automotive temperature range and are available in thermally enhanced 20-pin TSSOP or 16-pin TQFN packages. Features.
  • High-Efficiency Switcher Mode (Buck Mode) or Low-Quiescent-Current Linear Regulator (LDO Mode) Operation.
  • Wide Operating Input V.

www.DataSheet4U.com 19-0603; Rev 0; 7/06 40V, 600mA Buck Converters with LowQuiescent-Current Linear Regulator Mode General Description The MAX5096/MAX5097 easy-to-use, Dual Mode™, DC-DC converters operate as LDO (low dropout) or switch-mode buck converters. At a high output load, the converters operate as high-efficiency pulse-widthmodulated (PWM) switch-mode converters and reduce the power dissipation. The devices switch to a low-quiescent-current (IQ) LDO mode of operation at light load. During the key-off condition, the system’s microcontroller drives the LDO/BUCK input on the fly and forces the MAX5096/MAX5097 into LDO Mode, thereby reducing the quiescent current significantly.
