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
The LM5025B PWM controller contains all of the
features necessary to implement power converters
utilizing the Active Clamp / Reset technique. With the active clamp technique, higher efficiencies and
greater power densities can be realized compared to
conventional catch winding or RDC clamp / reset
techniques. Two control outputs are provided, the
main power switch control (OUT_A) and the active
clamp switch control (OUT_B). The two internal
compound gate drivers parallel both MOS and Bipolar
devices, providing superior gate drive characteristics.
This controller is designed for high-speed operation
including an oscillator frequency range up to 1MHz
and total PWM and current sense propagation delays
less than 100ns.
The LM5025B includes a high-voltage start-up
regulator that operates over a wide input range of
13V to 100V. Additional features include: Line Under
Voltage Lockout (UVLO), softstart, oscillator
UP/DOWN sync capability, precision reference and
thermal shutdown.
