LTC1159CS-3.3 Description

Short technical summary and product information.

The LTC1159CS-3.3 is a synchronous step-down switching regulator controller from LT, designed for high efficiency applications. It operates from an input voltage range of 4V to 40V and achieves up to 95% efficiency. This device features current mode operation for excellent transient response and very low dropout operation at 100% duty cycle.

 

The controller drives external complementary power MOSFETs at switching frequencies up to 250kHz. It automatically enters Burst Mode operation at low load currents to maintain high efficiency. In shutdown mode, the supply current is a low 20mA, and standby current is 300mA.

 

Available in SSOP and SO packages, the LTC1159CS-3.3 is suitable for various applications including notebook and palmtop computers, portable instruments, battery-operated digital devices, industrial power distribution, avionics systems, and telecom power supplies.
