LT3790EFE#PBF

LT3790 is a synchronous 4-switch buck-boost voltage/current regulator controller. It can regulate output voltage, output current, or input current with input voltages above, below, or equal to the output voltage. The constant-frequency, current mode architecture allows its frequency to be adjusted or synchronized from 200KHz to 700KHz. No top FET refresh switching cycle is needed in buck or boost operation. With 60V input, 60V output capability and seamless transitions between operating regions, this device is ideal for voltage regulator, battery/super-capacitor charger applications in automotive, industrial, telecom, and even battery-powered systems.

• Synchronous switching upto 98.5% efficiency
• Wide input voltage range is 4.7V to 60V
• 2% output voltage accuracy: 1.2V ≤ VOUT <lt/> 60V
• 6% output current accuracy: 0V ≤ VOUT <lt/> 60V
• Input and output current regulation with current monitor outputs
• No top FET refresh in buck or boost, capable of 100W or greater per IC
• VOUT disconnected from VIN during shutdown, easy parallel capability to extend output power
• C/10 charge termination and output shorted flags
• Operating temperature is -40°C to 125°C
• Packaging style is 38-lead plastic TSSOP
