LT1302
PRODUCTIONMicropower High Output Current Step-Up Adjustable and Fixed 5V DC/DC Converters
- Part Models
- 6
- 1ku List Price
- Starting From $6.08
Overview
- 5V at 600mA or 12V at 120mA from 2-Cell Supply
- 200µA Quiescent Current
- Logic Controlled Shutdown to 15µA
- Low VCESAT Switch: 310mV at 2A Typical
- Burst Mode™ Operation at Light Load
- Current Mode Operation for Excellent Line and Load Transient Response
- Available in 8-Lead SO or PDIP
- Operates with Supply Voltage as Low as 2V
The LT1302/LT1302-5 are micropower step-up DC/DC converters that maintain high efficiency over a wide range of output current. They operate from a supply voltage as low as 2V and feature automatic shifting between Burst Mode operation at light load, and current mode operation at heavy load.
The internal low loss NPN power switch can handle current in excess of 2A and switch at frequencies up to 400kHz. Quiescent current is just 200µA and can be further reduced to 15µA in shutdown.
Available in 8-pin PDIPor 8-pin SO packaging, the LT1302/LT1302-5 have the highest switch current rating of any similarly packaged switching regulators presently on the market.
