LT3693EMSE#PBF

LT3693 is an adjustable frequency (200KHz to 2.4MHz) monolithic buck switching regulator that accepts input voltages up to 36V. A high efficiency 95m switch is included on the die along with a boost schottky diode and the necessary oscillator, control, and logic circuitry. Current mode topology is used for fast transient response and good loop stability. Shutdown reduces input supply current to less than 1μA while a resistor and capacitor on the RUN/SS pin provide a controlled output voltage ramp (soft-start). A power good flag signals when VOUT reaches 91% of the programmed output voltage. Applications include automotive battery regulation, power for portable products, distributed supply regulation, industrial supplies and wall transformer regulation.

• Wide input range from 3.6V to 36V, 3.5A maximum output current
• Low shutdown current of IQ <lt/> 1μA
• Integrated boost diode, synchronizable between 250KHz to 2MHz
• Power good flag, saturating switch design, 95mohm on-resistance
• 0.790V feedback reference voltage, output voltage range from 0.79V to 30V
• Thermal protection, soft-start capability
• 10-lead plastic MSOP package, -40°C to 125°C temperature range
