PWM Off-Line Switching Regulator ICs

Features and Benefits

Description

STR3A100 series are power ICs for switching power supplies,

incorporating a power MOSFET and a current mode PWM

• Current mode PWM control

• Built-in Random Switching function: reduces

EMI noise, simplifies EMI filters, and cuts cost by

external part reduction

• Built-in Slope Compensation function: avoids

subharmonic oscillation

• Built-in Leading Edge Blanking (LEB) function

• Auto Standby function:

controller IC in one package.

Including a startup circuit and a standby function in the

controller, the product achieves low power consumption, low

standby power, and high cost-effectiveness in power supply

systems, while reducing external components.

▫ Input power, P_IN< 10 mW at no load with low power

consumption shunt regulator

The products are provided in an industry standard DIP8

package.

▫ Normal load operation: PWM switching

▫ Light load operation: Standby mode (Burst oscillation)

Applications

Switching power supplies for electronic devices such as:

• Stand-by power supply for LCD/PDP television,

desktop PC, multi-function printer, audio equipment,

and so forth

Package: DIP8

• Small switched-mode power supply (SMPS) for printer,

BD/DVD player, set-top box, and so forth

• Auxiliary power supply for air conditioner, refrigerator,

washer, dishwasher, and so forth
