NCP3133A 3 A Integrated Synchronous Buck Converter NCP3133A is a fully integrated synchronous buck converter for 3.3 V and 5 V step−down applications. It can provide up to 3 A load current. NCP3133A supports high efficiency, fast transient response and provides power good indicator. The control scheme includes two operation modes: FCCM and automatic CCM/DCM. In automatic CCM/DCM mode, the controller can smoothly switch between CCM and DCM, where converter runs at reduced switching frequency with much higher efficiency.

The automatic CCM/DCM mode operation provides reduced power loss and increases the efficiency at light load. The adaptive power control architecture enables smooth transition between light load and heavy load while maintaining fast response to load transients. NCP3133A is a low input voltage 3 A high performance synchronous buck converter with two integrated N−MOSFETs. NCP3133A’s output voltage range is from 0.6 V to 0.84 x Vin and it has wide input voltage range from 2.9 V to 5.5 V. The features of NCP3133A include supporting pre−bias start−up to protect sensitive loads, cycle−by−cycle over−current limiting and short circuit protection, power good monitor, over voltage and under voltage protection, built in output discharge and thermal shutdown. Operation Mode NCP3133A offers two operation modes programmed by PS pin connections, see table below. Table 5. PS pin Connection Operation Mode Auto Skip at Light Load (≤)174 kW to GND Automatic CCM/DCM Yes Floating or pulled to VDD FCCM Soft Stop In forced continuous conduction mode (FCCM), the high−side FET is ON during the on−time and the low−side FET is ON during the off−time. The switching is synchronized to an internal clock thus the switching frequency is fixed. In Automatic CCM/DCM mode, the high−side FET is ON during the on−time and low−side FET is ON during the off−time until the inductor current reaches zero. An internal zero−crossing comparator detects the zero crossing of the inductor current from positive to negative. When the inductor current reaches zero, the comparator sends a signal to the logic circuitry and turns off the low−side FET. When the load is increased, the inductor current is always positive and the zero−crossing comparator does not send any zero−crossing signal. The converter enters into continuous conduction mode (CCM) when no zero−crossing is detected for two consecutive PWM pulses. In CCM mode, the switching synchronizes to the internal clock and the switching frequency is fixed. Soft−Stop or discharge mode is always on during faults or disable. In this mode, a fault (UVP, OCP) or disable (EN) causes the output to be discharged through an internal 20 W transistor inside of SW terminal. The time constant of soft−stop is a function of output capacitance and the resistance of the discharge transistor. Automatic Power Saving Mode In Automatic CCM/DCM mode when the load current decreases, the converter will enter power saving mode operation. During power saving mode, the low−side MOSFET will turn off when the inductor current reaches zero. So the converter skips switching and operates with reduced frequency, which minimizes the quiescent current and maintains high efficiency. Forced Continuous Conduction Mode When PS pin is floating or pulled high, NCP3133A is operating in forced continuous conduction mode in both light load and heavy load conditions. In this mode, the switching frequency remains constant over the entire load range, making it suitable for applications that need tight regulation of switching frequency at a cost of lower efficiency at light load. Reference Voltage The NCP3133A incorporates 600 mV reference voltage with 1.0 % tolerance. Internal Soft−Start To limit the start−up inrush current, an internal soft start circuit is used to ramp up the reference voltage from 0 V to its final value linearly. The internal soft start time is 0.4 ms typically. http://onsemi.com 10 NCP3133A PROTECTIONS Under Voltage Lockout (UVLO) low−side FET exceeds 5.1 A, the over−current protection is enabled and immediately turns off both the high−side and the low−side FETs. The device is fully protected against over−current during both on−time and off−time. This protection is latched. There is under-voltage lock out protection (UVLO) for both VIN and VDD in NCP3133A, which has a typical trip threshold voltage 2.8 V and trip hysteresis 75 mV for VDD and 130 mV for VIN. If UVLO is triggered, the device resets and waits for the voltage to rise up over the threshold voltage and restart the part. Please note this protection function DOES NOT trigger the fault counter to latch off the part. Pre−Bias Startup In some applications the controller will be required to start switching when its output capacitors are charged anywhere from slightly above 0 V to just below the regulation voltage. This situation occurs for a number of reasons: the converter’s output capacitors may have residual charge on them or the converter’s output may be held up by a low current standby power supply. NCP3133A supports pre−bias start up by holding low−side FETs off until soft start ramp reaches the FB pin voltage. Over Voltage Protection (OVP) When feedback voltage is above 17% (typical) of nominal voltage for over 1.7 ms blanking time, an OV fault is set. In this case, the converter de−asserts the PGD signal and performs the over−voltage protection function. The top gate drive is turned off and the bottom gate drive is turned on to discharge the output. The bottom gate drive will be turned off until VFB drops below the UVP threshold. The device enters a high−impedance state. This protection is latched. Thermal Shutdown The NCP3133A protects itself from over heating with an internal thermal monitoring circuit. When the die temperature goes beyond a threshold value 135°C, both the high−side and the low−side FETs turn off until the temperature falls 40°C below of the threshold value. Then the converter restarts. Under Voltage Protection (UVP) Output under−voltage protection works in conjunction with the current protection described in the Over−current Protection sections. An UVP circuit monitors the feedback voltage to detect under−voltage event. The under−voltage limit is 17% (typical) below of nominal voltage at FB pin. If the feedback voltage is below this threshold over 11 ms, an UV fault is set and both the high−side and the low−side FETs turn off. This protection is latched. Application Note For higher output voltage application cases (Vout = 3.3 V), choose the inductor value not to be lower than 1 mH to avoid over-current protection being triggered by inductor current ripple; for higher output voltage application cases (Vout = 3.3 V), if the input power supply slew rate is too slow, consider to add a RC filter (100k and 1 mF) at EN pin to avoid any latch issue during the start up. Power Good Monitor (PGD) NCP3133A provides window comparator to monitor the output voltage at FB pin. When the output voltage is within ±17% of regulation voltage, the power good pin outputs a high signal. Otherwise, PGD stays low. The PGD pin is open drain 5 mA pull down output. During startup, PGD stays low until the feedback voltage is within the specified range for about 0.4 ms. If feedback voltage falls outside the tolerance band, the PG pin goes low after 10 ms delay. The PGD pin de−asserts as soon as the EN pin is pulled low or an under−voltage event on VDD is detected. Layout Guidelines When laying out a power PCB for the NCP3133A there are several key points to consider. Use four vias to connect the thermal pad to power ground. Separate the power ground and analog ground planes; connect them together at a single point. Increase the thickness of PCB copper, it can help to lower the die temperature and improve the overall efficiency but meanwhile increase the cost of the board fabrication. Use wide traces for the nodes conducting high current such as VIN, VOUT, PGND and SW. Place feedback and compensation network components close to the IC. Keep FB, COMP away from noisy signals such as SW, BST. Place VIN and VDD decoupling capacitors as close to the IC as possible. Over Current Protection (OCP) NCP3133A provides both high−side and low−side MOSFET current limiting. When the current through the high−side FET exceeds 4.8 A, the high−side FET turns off and the low−side FET turns on until next PWM cycle. An over−current counter is triggered and starts to increment each occurrence of an over−current event. Both the high−side and the low−side FETs turn off when the OC counter reaches four. The OC counter resets if the detected current is less than 4.8 A after an OC event. Another set of over−current circuitry monitors the current flowing through the low−side FET.
