DC-DC преобразователи интегральные MAX633ACSA+

Повышающий , импульсный стабилизатор, фиксированный, 1.5В до 16.5В, 15В/50мА выход, 50кГц, NSOIC-8

The MAX633ACSA+ from Maxim Integrated Products is a CMOS fixed/adjustable output, step-up switching regulator in 8 pin NSOIC package. This device preset output is 15V, step-up DC to DC converter for use in low power, high efficiency switching regulator applications. It has an on-chip low battery detection circuitry and a charge pump output for generating a negative voltage in dual supply applications. The only external components required are an output filter capacitor and a low cost inductor. This device can be set to other output voltages by adding an external voltage divider. It is used in minimum components, high efficiency DC-DC converters, portable instruments, rechargable and primary battery power conversion, uninterruptable on-board power supplies, card level multiple power conversion.

• Adjustable output with 2 resistors
• Operating temperature range from -0°C to 70°C
• Charge pump for negative output
• Switching frequency of 50KHz (typ)
• Operating current of 135µA
• 80% typical efficiency
• 5% output accuracy
• Only 2 external components (output filter capacitor, low-cost inductor)
