NXP GreenChip
Synchronous Rectification
controller TEA1792
The next level in adapter efficiency
Optimized`for`use`in`power`adapters,`this`next-generation`GreenChip`device`enables`low`current`
consumption,`high`system`efficiency,`and`a`reduced`bill`of`materials.
Key features
The`NXP`TEA1792`is`a`GreenChip`IC`dedicated`to`control`
Synchronous`Rectification`on`the`secondary`side`of`discontinuous`
mode`and`quasi-resonant`flyback`converters.`
`` `Small,`industry`standard`TSOP6`package`enabling`compact`
applications
`` Accurate`Synchronous`Rectification`functionality
`` Wide`supply`voltage`range`(8.5`to`38`V)
`` High`level`of`integration,`resulting`in`a`very`low`external`
component`count
As`a`member`of`NXP’s`new`generation`of`GreenChip`Synchronous`
Rectifier`controller`ICs`for`switched`mode`power`supplies,`it`offers`
a`very`high`level`of`integration.`The`result`is`a`cost-effective`power`
`` High`driver`output`voltage`of`10`V`to`drive`all`MOSFET`brands` supply`with`a`very`low`number`of`external`components`with`a`
to`the`lowest`RDSon
compact`size.`
`` Selectable`regulation`level`for`driver`stage
`` `Low`current`consumption
GreenChip
`` `High`system`efficiency`from`no`load`to`full`load
`` `UnderVoltage`Protection`(UVP)
`` `Also`available`in`SO8`package
NXP’s`GreenChip`family`makes`it`easier`and`more`cost-effective`
for`power`supply`manufacturers`to`comply`with`energy`efficiency`
specifications`such`as`ENERGY`STAR®`and`ErP`lot`6`(EuP`lot`6).`
The`GreenChip`family`is`designed`specifically`for`energy`saving`
and`has,`from`its`inception,`led`industry`standards`in`PC`power`
efficiency,`especially`in`portable`formats.
