The maximum allowable continuous power dissipation at any ambient temperature is calculated by P D (MAX) = (T J (MAX)-TA)/θJA. Exceeding the maximum allowable powe r dissipation produces an excessive die temperature, causing the regulator to go into thermal shutdown. Internal thermal shutdown circuitry protects the device from permanent damage. 3) The device is not guaranteed to function outside of its operating conditions. 4) Measured on EV2172C-Q-00A demo board, 2-layer PCB. 5) Measured onJESD51-7, 4-layer PCB. note 5) The value of θJA given in this table is only valid for comparison with other packages and cannot be used for design purposes. These values are calculated in accordance with JESD51-7, and simulated on a specified JEDEC board. They do not represent the performance obtained in an actual application

Unauthorized Photocopy and Duplication Prohibited. © 2019 MPS. All Rights Reserved. OPERATION The MP2172C uses constant-on-time (COT) control with input voltage feed-forward to stabilize the switching frequency over the entire input range. The part achieves 2A of continuous output current from a 2.38V to 5.5V input voltage range with excellent load and line regulation. The output voltage can be regulated as low as 0.6V. Constant-On-Time (COT) Control Constant-on-time (COT) control offers a simpler control loop and faster transient response than fixed-frequency pulse-width modulation (PWM) control. By using input voltage feed-forward, the MP2172C maintains a nearly constant switching frequency across the input and output voltage ranges. The switching pulse on time can be estimated with Equation (1): OUT ON IN To prevent inductor current runaway during the load transient, the MP2172C has a fixed minimum off time of 100ns. Force PWM Operation The MP2172C works in continuous current mode (CCM) to achieve a smaller V O ripple, load regulation, and load transient in full-load range. Enable (EN) If the input voltage is greater than the under- voltage lockout (UVLO) threshold (typically 2.3V), the MP2172C can be enabled by pulling EN higher than 1.2V. Leave EN floating or pull EN down to ground to disable the MP2172C. There is an internal 1M Ω resistor from EN to ground. When the device is disabled, the MP2172C enters output discharge mode automatically. Its internal discharge MOSFET provides a resistive discharge path for the output capacitor. Soft Start (SS) The MP2172C has a built-in soft start that ramps up the output voltage at a controlled slew rate to avoid overshooting at start-up. The soft- start time is typically about 0.5ms. Current Limit The MP2172C has a typical minimum 2.8A high-side switch current limit. When the high- side switch reaches its current limit, the MP2172C remains in hiccup mode until the current drops. This prevents the inductor current from continuing to rise and damaging components. Short Circuit and Recovery The MP2172C enters short-circuit protection (SCP) mode when it reaches its current limit, and attempts to recover with hiccup mode. The part disables the output power stage, discharges the soft-start capacitor, and attempts to soft start again automatically. If the short-circuit condition remains after the soft start ends, the MP2172C repeats this cycle until the short circuit is removed and the output rises back to the regulation level. Over-Voltage Protection (OVP) The MP2172C monitors the feedback voltage to detect over-voltage. When the feedback voltage FB) exceeds 115% of the target voltage, the controller enters a dynamic regulation period. During this period, the low-side MOSFET (LS- FET) turns on until the low-side current drops to -1.5A. This discharges the output to keep it within the normal range. If the over-voltage condition still remains, the LS-FET turns on again after a 1µs delay. The MP2172C exits this regulation period when V FB falls below 105% of the reference voltage. If the dynamic regulation cannot limit the increasing V OUT, once the input detects the 6.1V input, over-voltage protection (OVP) occurs. The MP2172C stops switching until the input voltage drops below 5.7V, and then the part resumes operation.

For simplification, choose an input capacitor with an RMS current rating greater than half of the maximum load current. The input capacitor can be electrolytic, tantalum, or ceramic. When using electrolytic or tantalum capacitors, add a small, high-quality 0.1 μF ceramic capacitor as close to the IC as possible. When using ceramic capacitors, ensure that they have enough capacitance to provide a sufficient charge to prevent excessive voltage ripple at the input. The input voltage ripple caused by the capacitance can be estimated with Equation (7): LOAD OUT OUT IN INSI N IV VV1 fC 1V V (7) Selecting the Output Capacitor The output capacitor (C2) stabilizes the DC output voltage. Low ESR ceramic capacitors are recommended to limit the output voltage ripple. Estimate the output voltage ripple with Equation (8): OUT OUT OUT ESR S1 I N S VV 1V1 R fL V 8 fC 2 (8) Where L1 is the inductor value, and R ESR is the equivalent series resistance (ESR) value of the output capacitor. When using ceramic capacitors, the capacitance dominates the impedance at the switching frequency and causes most of the output voltage ripple. For simplification, the output voltage ripple can be estimated with Equation (9): OUT OUT OUT 2 S1 I N VV∆V1 8f L C 2 V (9) For tantalum or electrolytic capacitors, the ESR dominates the impedance at the switching frequency. For simplification, the output ripple can be approximated with Equation (10): OUT OUT OUT ESR INS1 VV∆V1 R fL V (10) The characteristics of the output capacitor also affect the stability of the regulation system. PCB Layout Guidelines Efficient PCB layout is critical for stable operation. For the high-frequency switching converter, improper layout design can result in poor line or load regulat ion and stability issues. For best results, refer to Figure 10 and follow the guidelines below: 1. Place the high-current paths (GND, VIN, and SW) very close to the device with short, direct, and wide traces. 2. Place the input capacitor as close to VIN and GND as possible. 3. Place the external feedback resistors next to FB. 4. Keep SW short and away from the feedback network. 5. Keep the V OUT sense line need as short as possible and away from the power inductor, especially the surrounding inductor. Figure 10: Recommended Layout for the MP2172C
