1 General Description
The AS1390A, AS1390B is a high-power, constant-frequency boost
controller with an integrated buck converter. The AS1390A can be
used for the boost converter in TV sets which are optimized for 2D
and 3D mode. AS1390B is designed for single mode operation.
The continuous conduction mode of the AS1390 provides superior
bandwidth and transient response. The two output voltages for the
boost controller (2D and 3D mode) can be programmed with an
external resistor divider.
The buck converter is optimized for suppling a µP with 5V.
The AS1390A is available in a 20-pin QFN (4x4mm) package, the
AS1390B comes in a 16-pin SOIC package.
2 Key Features
