These devices have the same pin configuration as the UC2842/3/4/5 family and also offer the added features of internal full-cycle soft start and internal leading-edge blanking of the current-sense input. The UCC2813-0/-1/-2/-3/-4/-5 family offers choice of maximum duty cycle and critical voltage levels. Lower reference parts, such as the UCC2813-3 and UCC2813-5, fit best into battery-operated systems, while the higher reference and the higher undervoltage lockout (UVLO) hysteresis of the UCC2813-2 and UCC2813-4 make these ideal choices for use in off-line power supplies. The UCC2813-x series is specified for the automotive temperature range of −40_C to 125_C.

POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 5 SGLS245D − MAY 2004 − REVISED APRIL 2008 detailed terminal descriptions COMP COMP is the output of the error amplifier and the input of the PWM comparator. Unlike other devices, the error amplifier in the UCC2813 family is a true, low output-impedance, 2-MHz operational amplifier. As such, the COMP terminal can both source and sink current. However, the error amplifier is internally current limited, so that one can command zero duty cycle by externally forcing COMP to GND. The UCC2813 family features built-in full-cycle soft start. Soft start is implemented as a clamp on the maximum COMP voltage. CS CS is the input to the current sense comparators. The UCC2813 family has two different current sense comparators: the PWM comparator and an overcurrent comparator. The UCC2813 family contains digital current sense filtering, which disconnects the CS terminal from the current sense comparator during the 100 ns interval immediately following the rising edge of the OUT pin. This digital filtering, also called leading-edge blanking, means that in most applications, no analog filtering (RC filter) is required on CS. Compared to an external RC filter technique, the leading-edge blanking provides a smaller effective CS to OUT propagation delay. Note, however, that the minimum non-zero on time of the OUT signal is directly affected by the leading-edge blanking and the CS to OUT propagation delay. The overcurrent comparator is only intended for fault sensing, and exceeding the overcurrent threshold causes a soft start cycle. FB FB is the inverting input of the error amplifier. For best stability, keep FB lead length as short as possible and FB stray capacitance as small as possible. GND GND is reference ground and power ground for all functions on this part. OUT OUT is the output of a high-current power driver capable of driving the gate of a power MOSFET with peak currents exceeding "750 mA. OUT is actively held low when VCC is below the UVLO threshold. The high-current power driver consists of FET output devices, which can switch all of the way to GND and all of the way to VCC. The output stage also provides a low impedance to overshoot and undershoot. This means that, in many cases, external Schottky clamp diodes are not required. 6 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 SGLS245D − MAY 2004 − REVISED APRIL 2008 detailed descriptions (continued) RC RC is the oscillator timing pin. For fixed frequency operation, set timing capacitor charging current by connecting a resistor from REF to RC. Set frequency by connecting timing capacitor from RC to GND. For best perfomance, keep the timing capacitor lead to GND as short and direct as possible. If possible, use separate ground traces for the timing capacitor and all other functions. The frequency of oscillation can be estimated with the following equations: UCC2813−0ń1ń2ń4 : F + 1.5 R C UCC2813−3ńUCC2813−5 : F + 1.0 R C (1) where frequency is in Hz, resistance is in ohms, and capacitance is in farads. The recommended range of the timing resistors is between 10 kΩ and 200 kΩ and the timing capacitor is 100 pF to 1000 pF. Never use a timing resistor less than 10 k. To prevent noise problems, bypass VCC to GND with a ceramic capacitor as close to the VCC pin as possible. An electrolytic capacitor may also be used in addition to the ceramic capacitor. voltage reference (REF) REF is the voltage reference for the error amplifier and also for many other functions on the IC. REF is also used as the logic power supply for high-speed switching logic on the IC. When VCC is greater than 1 V and less than the UVLO threshold, REF is pulled to ground through a 5-kΩ resistor. This means that REF can be used as a logic output indicating power system status. It is important for reference stability that REF is bypassed to GND with a ceramic capacitor as close to the pin as possible. An electrolytic capacitor may also be used in addition to the ceramic capacitor. A minimum of 0.1-µF ceramic capacitor is required. Additional REF bypassing is required for external loads greater than 2.5 mA on the reference. To prevent noise problems with high-speed switching transients, bypass REF to ground with a ceramic capacitor close to the IC package. power (VCC) VCC is the power input connection for this device. In normal operation, VCC is powered through a current-limiting resistor. Although quiescent VCC current is low, total supply current will be higher, depending on OUT current. Total VCC current is the sum of quiescent VCC current and the average OUT current. Knowing the operating frequency and the MOSFET gate charge (Qg), average OUT current can be calculated from: I OUT + Q g F.

The rise time is set by the time constant of RT and CT. The fall time is set by CT and an internal transistor on-resistance of approximately 125. During the fall time, the output is off and the maximum duty cycle is reduced below 50% or 100% depending on the part number. Larger timing capacitors increase the discharge time and reduce the maximum duty cycle and frequency.
