LT3505EMS8E#PBF

LT®3505 is a current mode PWM step-down DC/DC converter with an internal 1.4A power switch. Ideal for regulating power from a wide variety of sources, including unregulated wall transformers, 24V industrial supplies and automotive batteries. The oscillator can be programmed for high frequency operation allowing the use of tiny, low cost external components or it can be programmed for lower frequency operation to maximize efficiency. Cycle-by-cycle current limit provides protection against shorted outputs and soft-start eliminates input current surge during start-up. Typical applications are automotive battery regulation, industrial control supplies, wall transformer regulation, distributed supply regulation, battery-powered equipment.

• Wide input range is 3.6V to 36V operating, 40V maximum
• 1.2A output current
• Resistor-programmable fixed-frequency operation from 200kHz to 3MHz
• Output adjustable down to 780mV
• Short-circuit robust, soft-start
• Uses tiny capacitors and inductors
• Low shutdown current is <lt/>2µA
• Low VCESAT switch is 350mV at 1A
• 8-lead plastic MSOP package
• –40°C to 85°C temperature range
