Регуляторы напряжения - Импульсные регуляторы MIC2619YD6 TR

Импульсный повышающий DC-DC стабилизатор , регулируемый, 2.8В-6.5В (Vin), 2.8В-35В, 350мА, SOT-23-6

The MIC2619YD6 TR is a step-up Switching Regulator optimized for low power and high output voltage applications. With a maximum output voltage of 35V and a switch current of over 350mA, the MIC2619 can easily supply most high voltage bias applications, such as TV tuners. The MIC2619 implements a constant frequency 1.2MHz PWM current-mode control scheme. The high frequency PWM operation saves board space by reducing external component sizes. The additional benefit of the constant frequency PWM control scheme as opposed to variable frequency control schemes is lower output noise and smaller input ripple injected back to the battery source. The MIC2619 has programmable overvoltage protection to ensure output protection in case of fault condition.

• Programmable overvoltage protection (OVP)
• Over-temperature protection
• Undervoltage lockout (UVLO)
• 1.265V Feedback voltage
• <1% Line regulation
• <1µA Shutdown current
