BCT3401

The BCT3401 is a high efficiency synchronous DC-DC step-down converter designed to drive LED, using a constant frequency and current. The 100% duty cycle ,Automatic PWM/PFM mode and a low 100mV feedback voltage minimizes power loss in the current setting resistor ,these feature increases efficiency, extending battery life in portable systems.

At shutdown mode, the input supply current is less than 1µA.
The current limit protection features provide protection against any combination of overload.
The BCT3401 is available in a 5-pin SOT23-5 package, which provides a compact solution with minimal external components.

FEATURES
2.5V~5.5V Input Voltage Range
1.2A Output Current
1.5MHz Switching Frequency Minimizes the External Components
Shutdown Current :<1µA
Up to 92% efficiency
100% Duty Cycle in Dropout Operation
Internal soft-start
PWM dimming
Output short protection
Thermal Protection
SOT23-5 Packages

APPLICATIONS
LED Driver
