The LTC1147CS8-3.3#PBF is a high-efficiency step-down switching regulator controller designed by Linear Technology. It features automatic Burst Mode operation to maintain high efficiencies at low output currents. This controller operates with a wide input supply range from 3.5V to 16V, making it suitable for various battery-powered applications.
Key electrical characteristics include current mode operation for excellent transient response, low standby current of 160mA at light loads, and micropower shutdown mode with IQ < 20mA. The device supports very low dropout operation with 100% duty cycle capability. It drives an external P-channel power MOSFET at switching frequencies exceeding 400kHz.
Available in an 8-pin SO package, the LTC1147CS8-3.3#PBF is designed for surface mount applications. Its design allows for high efficiency to be maintained over a wide range of output currents, making it a versatile choice for portable instruments, notebook computers, and battery-operated digital devices.
This controller incorporates features such as short-circuit protection and logic-controlled shutdown. The constant off-time architecture provides precise control over inductor ripple current and enables low dropout regulation.
