LT3509 - 700mA Step-Down Regulator

General Description

The LT®3509 is a dual, current mode, step-down switching regulator, with internal power switches each capable of providing 700mA output current.

This regulator provides a compact and robust solution for multi-rail systems in harsh environments.

Key Features

  • including overvoltage lockout and cycle by cycle current limit. Thermal shutdown provides additional protection. The loop compensation components and the boost diodes are integrated on-chip. Switching frequency is set by a single external resistor. External synchronization is also possible. The high maximum switching frequency allows the use of small inductors and ceramic capacitors for low ripple. Constant frequency operation above the AM band avoids interference with radio reception, making th.
