Linear Technology
DESCRIPTION
The LT®1766/LT1766-5 are 200kHz monolithic buck switch ing regulators that accept input voltages up to 60V. A high effi ciency 1.5A, 0.2Ω switch is included on the die along with all the necessary oscillator, control and logic circuitry. A current mode control architecture delivers fast transient response and excellent loop stability.
