DESCRIPTION
The LM5025C is a functional variant of the LM5025
active clamp PWM controller. The functional
differences of the LM5025C are: The maximum duty
cycle of the LM5025C is increased from 80% to 91%.
The soft-start capacitor charging current is increased
from 20 μA to 90 μA. The VCC regulator current limit
threshold is increased from 25 mA to 55 mA. The
CS1 and CS2 current limit thresholds have been
increased to 0.5V. The internal CS2 filter discharge
device has been disabled and no longer operates
each clock cycle. The internal VCC and VREF
regulators continue to operate when the line UVLO
pin is below threshold.
The LM5025C 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 100 ns. The LM5025C includes a highvoltage
start-up regulator that operates over a wide
input range of 13V to 90V. Additional features
include: Line Under Voltage Lockout (UVLO),
softstart, oscillator UP/DOWN sync capability,
precision reference and thermal shutdown.
