■ ■ DESCRIPTIO The LT ®1680 is a high power, current mode switching
power supply controller optimized for boost topologies.
The IC drives an N-channel MOSFET switch for DC/DC
converter applications up to 60V input. A high current gate
drive output handles up to 10,000pF gate capacitance,
enabling the construction of high power DC/DC converters. Current sense common mode range up to 60V allows
current sensing to be referenced to the input supply,
eliminating the need for sense blanking circuits. High Voltage: Operation Up to 60V
High Current: N-Channel Drive Handles Up to
10,000pF Gate Capacitance
Programmable Average Current Limiting
5V Reference Output with 10mA External
Loading Capability
Fixed Frequency Current Mode Operation
Oscillator Synchronizable Up to 200kHz …
