Регуляторы напряжения - Импульсные регуляторы MAX759CPD+

Импульсный инвертирующий DC/DC стабилизатор , регулируемый, 4В до 11В вход, -15В/300 мА выход, 185кГц

The MAX759CPD+ from Maxim Integrated Products is a CMOS inverting current mode PWM regulator in 14 pin DIP package. This inverting, switch mode regulator with an internal power MOSFET employ a high-performance, current mode, pulse width modulation control scheme to provide tight output voltage regulation and low noise. The fixed frequency oscillator is factory trimmed to 165KHz allowing easy noise filtering. The device is product tested in actual application circuit and output accuracy at ±5% over all specified conditions of line, load and temperature. It is used in low noise analogue signal processing circuits, LCD bias supplies, power supplies for ECL, board-level DC-DC conversion, battery powered equipment and computer peripherals.

• Input voltage range is 4V to 11V
