LT1613CS5#TRPBF

LT1613 is a current mode DC/DC converter. Intended for small, low power applications, it operates from an input voltage as low as 1.1V and switches at 1.4MHz, allowing the use of tiny, low cost capacitors and inductors 2mm or less in height. Its small size and high switching frequency enables the complete DC/DC converter function to take up less than 0.2 square inches of PC board area. Multiple output power supplies can now use a separate regulator for each output voltage, replacing cumbersome quasi-regulated approaches using a single regulator and a custom transformer. A constant frequency, internally compensated current mode PWM architecture results in low, predictable output noise that is easy to filter. It is widely used in application such as digital cameras, pagers, cordless phones, battery backup, LCD bias, medical diagnostic equipment, local 5V or 12V supply, external modems, PC cards etc.

• Low VCESAT switch is 300mV typical at 300mA
• Quiescent current is 3mA typical at (VSHDN = 1.5V)
• Operating temperature is 0°C to 70°C
• Package style is 5-lead plastic SOT-23
