Product Overview
LT3845 is a high voltage, synchronous, current mode controller used for medium to high power, high efficiency supplies. It offers a wide 4V to 60V input range (7.5V minimum start-up voltage). An onboard regulator simplifies the biasing requirements by providing IC power directly from VIN. Burst Mode® operation maintains high efficiency at light loads by reducing IC quiescent current to 120μA. Additional features include adjustable fixed operating frequency that can be synchronized to an external clock for noise sensitive applications, gate drivers capable of driving large N-channel MOSFETs, a precision undervoltage lockout, 10μA shutdown current, short-circuit protection and a programmable soft-start. It is used in application such as 12V and 42V automotive and heavy equipment, 48V telecom power supplies, avionics and industrial control systems, distributed power converters etc.
- External sync frequency range is 100KHz to 600KHz
- Output voltages upto 36V, adaptive nonoverlap circuitry prevents switch shoot-through
- Programmable soft-start, reverse overcurrent protection
- Standard gate N-channel power MOSFETs, current limit unaffected by duty cycle
- No load quiescent current is 120μA
- Supply current is 20μA typical
- Operating junction temperature is -40°C to 125°C
- Package style is 16-lead plastic TSSOP
