Регуляторы напряжения - Импульсные регуляторы MAX755CSA+

Импульсный инвертирующий DC-DC стабилизатор , регулируемый, 2.7В-9В вход, -5.25В--4.75В/175мА

The MAX755CSA+ from Maxim Integrated Products is a -5V/adjustable negative output, inverting, current mode PWM regulator in 8 pin NSOIC package. The power conserving features along with high efficiency and applications circuits that lend themselves to miniaturization makes the excel in a board range of on-card and portable equipment applications. It employs a high performance current mode pulse width modulation control scheme to provide tight output voltage regulation and low subharmonic noise. The fixed frequency oscillator is factory trimmed to 160KHz allowing for easy noise filtering. Regulator is production tested in actual application circuits and output accuracy is guaranteed to within ±5% over all specified condition of line, load and temperature. Typically used at board level DC-DC conversion, battery powered equipment and computer peripherals.
