LT3682
1A Micropower Step-Down
Switching Regulator
FEATURES DESCRIPTION n The LT®3682 is an adjustable frequency (250kHz to
2.2MHz) monolithic buck switching regulator that accepts
input voltages up to 36V. A high efficiency 0.5Ω switch is
included on the device along with a boost diode and the
necessary oscillator, control, and logic circuitry. Current
mode topology is used for fast transient response and good
loop stability. A SYNC pin allows the user to synchronize the
part to an external clock, and to choose between Low Ripple
Burst Mode operation and standard PWM operation. Wide Input Range:
Operation from 3.6V to 36V
Overvoltage Lockout Protects Circuits through
60V Transients
1A Output Current
Low Ripple Burst Mode® Operation
IQ = 75μA at 12VIN to 3.3VOUT
Output Ripple < 15mVP-P
Adjustable Switching Frequency: 250kHz to 2.2MHz
Short-Circuit Protected
Synchronizable Between 300kHz and 2.2MHz
0.8V Feedback Reference Voltage …
