DESCRIPTION
The TPS92010 is a PWM controller with advanced
energy features to provide high efficiency driving for
LED lighting applications.
The TPS92010 incorporates frequency fold back and
low power mode operation to reduce the operation
frequency at light load and no load operations.
The TPS92010 is offered in the 8-pin SOIC (D)
package. Operating junction temperature range is
–40°C to 105°C.
