The NCV887103D1R2G is an automotive-grade non-synchronous boost (step-up) DC-DC controller from ON Semiconductor. Designed specifically for automotive applications, this controller is AEC-Q100 qualified and PPAP capable, ensuring it meets the rigorous quality and reliability standards of the automotive industry. The NCV8871 series uses peak current mode control with internal slope compensation for stable operation over a wide range of input and output conditions. The ’03’ in the part number indicates a 340kHz fixed switching frequency version, while the ‘D’ suffix specifies SOIC-8 package. The wide input voltage range of 3.2V to 40V (with 45V load dump tolerance) makes this device suitable for automotive 12V systems where input voltage can vary widely during cold crank, load dump, and start-stop operation. The controller drives an external N-channel MOSFET, allowing the power stage to be sized for the specific application requirements. Key features include internal soft-start for controlled startup, undervoltage lockout (UVLO) for proper operation at low input voltages, and comprehensive protection including cycle-by-cycle current limiting, hiccup-mode overcurrent and short-circuit protection, and thermal shutdown. The low quiescent current sleep mode (100µA) is useful for battery-powered systems that need to minimize standby power consumption. The NCV887103D1R2G can also be used in flyback converter configurations, adding versatility for isolated power supply designs.

The NCV887103D1R2G operates as a peak current mode controlled boost (step-up) DC-DC controller: 1) Oscillator and Timing: The internal oscillator generates a fixed 340kHz clock that sets the switching frequency. The oscillator can also be synchronized to an external clock signal via the SYNC pin for applications requiring frequency synchronization. 2) Error Amplifier and Compensation: An error amplifier compares the feedback voltage (sensed from the output through a resistor divider) to the 1.2V internal reference voltage. The output of the error amplifier (COMP pin) sets the peak current threshold for each switching cycle. 3) Current Mode Control: At the start of each clock cycle, the external MOSFET is turned on. The inductor current ramps up, and this current is sensed (through a sense resistor in series with the MOSFET source). When the sensed current reaches the threshold set by the error amplifier, the MOSFET is turned off. This is peak current mode control. Internal slope compensation adds a stabilizing ramp to the current sense signal to prevent sub-harmonic oscillation at duty cycles above 50%. 4) Gate Drive: The GATE pin directly drives the gate of the external N-channel MOSFET. The gate driver provides 575mA of peak drive current for fast switching transitions. 5) Output Diode: When the MOSFET is off, the inductor current flows through an external Schottky diode (non-synchronous) to charge the output capacitor and supply the load. 6) Soft-Start: An internal soft-start circuit gradually increases the current limit during startup, preventing excessive inrush current and output voltage overshoot. 7) Protection: – UVLO: Ensures the controller only operates when VCC is above the minimum threshold. – OCP/SCP: Cycle-by-cycle current limit prevents excessive current; hiccup mode provides short-circuit protection. – TSD: Thermal shutdown protects the IC from overheating. 8) Sleep Mode: When the EN/UVLO pin is pulled low, the controller enters a low-power sleep mode with only 100µA quiescent current, preserving battery life.
