Part Number : LM5025B
Function : Active Clamp Voltage Mode PWM Controller
Package : TSSOP 16 Pin Type
Maker : Texas Instruments
Pinouts :
Description :
The LM5025B is a functional variant of the LM5025 active clamp PWM controller.
The functional differences of the LM5025B are as follows:
• The maximum PWM duty cycle is limited to less than 75% to reduce voltage stress on the power MOSFETs.
• The CS2 hiccup mode threshold is increased to 0.5V
• The CS2 filter discharge device is disabled
• The Vcc regulator continues to operate when the line UVLO is below the threshold of normal operation
• The Vref regulator is switched off when the line UVLO input falls below the operating threshold
• The internal 5kΩ COMP pin pull-up resistor is removed
Features
• Internal Start-Up Bias Regulator
