LT3580
Boost/Inverting DC/DC
Converter with 2A Switch,
Soft-Start, and Synchronization
FEATURES DESCRIPTION n The LT®3580 is a PWM DC/DC converter containing an
internal 2A, 42V switch. The LT3580 can be configured
as either a boost, SEPIC or inverting converter. Capable
of generating 12V at 550mA or –12V at 350mA from a
5V input, the LT3580 is ideal for many local power supply
designs. 2A Internal Power Switch
Adjustable Switching Frequency
Single Feedback Resistor Sets VOUT
Synchronizable to External Clock
High Gain SHDN Pin Accepts Slowly Varying
Input Signals
Wide Input Voltage Range: 2.5V to 32V
Low VCESAT Switch: 300mV at 1.5A (Typical)
Integrated Soft-Start Function
Easily Configurable as a Boost or Inverting Converter
User Configurable Undervoltage Lockout (UVLO)
Tiny 8-Lead 3mm × 3mm DFN and 8-Lead MSOP
Packages APPLICATIONS n The LT3580 has an adjustable oscillator, set by a resistor
from the RT pin to ground. Additionally, the LT3580 can …
