LT1766/LT1766-5
5.5V to 60V 1.5A, 200kHz
Step-Down Switching Regulator
FEATURES DESCRIPTION n The LT®1766/LT1766-5 are 200kHz monolithic buck switching regulators that accept input voltages up to 60V. A high
efficiency 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. n Wide Input Range: 5.5V to 60V
