Linear Technology LT3500

the LT3500 suitable for regulating power from a wide variety of sources, including automotive batteries, 24V industrial supplies and unregulated wall adapters. The soft-start feature controls the ramp rate of the output voltage, eliminating input current surge during start-up, and also provides output tracking. The LT3500 contains an internal NPN transistor with feedback control which can be conﬁgured as a linear regulator or as a linear regulator controller.

DESCRIPTION

The LT®3500 is a current mode PWM step-down DC/DC converter with an internal 2.3A switch. The wide input range of 3V to 40V makes Resistor-programmable 250kHz to 2.2MHz frequency range and synchronization capability enable optimization between efﬁciency and external component size. Cycleby-cycle current limit, frequency foldback and thermal shutdown provide protection against a shorted output. The LT3500’s low current shutdown mode (<12μA) enables easy power management in battery-powered systems. L, LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
