WPMDB1400362Q / 171040302 MagI3C Power Module VDRM – Variable Step Down Regulator Module LIGHT LOAD OPERATION The 171040302 forces the CCM (Continuous Conduction Mode) operation at light load (forced CCM). The inductor current during tOFF can flow in the opposite direction, i.e. from the output capacitor and load to ground, through the low side MOSFET. In this way during tOFF the output capacitor is discharged and loses the excess of charge gathered during t ON.

WPMDB1400362Q / 171040302 MagI3C Power Module VDRM – Variable Step Down Regulator Module Step 3 Select input capacitor (CIN) The energy at the input of the power module is stored in the input capacitor. A small input capacitor (100nF) is integrated inside the 1710x0302 MagI³C Power Module series, ensuring good EMI performance. Additional input capacitance is required external to the power module to provide cycle-by-cycle switch current and to support load transients.

WPMDB1400362Q / 171040302 MagI3C Power Module VDRM – Variable Step Down Regulator Module The use of very low ESR capacitors leads to an output voltage ripple as shown below: Output voltage ripple with low ESR capacitors Output voltage ripple [mV] 10 5 0 -5 -10 0 1 2 3 time [µs] When capacitors with slightly higher ESR are utilized, the dominant parameter which influences the output voltage ripple is just the ESR: ESR ≤ V ∆I (7) Consequently the shape of the output voltage ripple changes, as
PAGE 24
WPMDB1400362Q / 171040302 MagI3C Power Module VDRM – Variable Step Down Regulator Module Selection by load step requirements The output voltage is also affected by load transients (see picture below). When the output current transitions from a low to a high value, the voltage at the output capacitor (V OUT) drops. This involves two contributing factors. One is caused by the voltage drop across the ESR (V ESR) and depends on the slope of the rising edge of the current step (t rise).
PAGE 25
WPMDB1400362Q / 171040302 MagI3C Power Module VDRM – Variable Step Down Regulator Module In order to choose the value of the output capacitor, the following steps should be utilized: 1. 2. 3. According to the operating conditions (VIN, VOUT and fSW ), select the minimum COUT recommended in table on page 35. Measure td. Calculate the appropriate value of COUT for the maximum voltage drop Vdischarge allowed at a defined load step, using the following equation (10), derived from equation (9): C 4.

WPMDB1400362Q / 171040302 MagI3C Power Module VDRM – Variable Step Down Regulator Module Nevertheless, as indicated in point 4, one or more measurements should be performed in order to find the most suitable value of COUT. After some iterations, the most suitable output capacitance is determined. Due to its high value, a combination of two MLCC (47µF each one) and an electrolytic capacitor (220µF) is implemented.

Adding additional capacitance between the SS/TRK pin and AGND increases the soft-start time according to the table below. There is no maximum value limit for CSS.

The first peak (same for any condition) is due to the initial charge of the capacitors at the input (C IN). This current peak is not affected by the soft-start.

WPMDB1400362Q / 171040302 MagI3C Power Module VDRM – Variable Step Down Regulator Module LAYOUT RECOMMENDATION PCB layout is an important part of DC-DC converter design. Poor board layout can interfere with the performance of a DC-DC converter and surrounding circuitry by contributing to EMI, ground bounce and resistive voltage drop in the traces. These can send erroneous signals to the DC-DC converter resulting in poor regulation or instability.

If not properly handled, poor grounding can result in degraded load regulation or erratic output voltage ripple behavior. Place R RT, and CSS close to their respective pins.
PAGE 39
WPMDB1400362Q / 171040302 MagI3C Power Module VDRM – Variable Step Down Regulator Module 4: Feedback layout ENABLE The feedback resistor, RSET should be located close to the FB pin. Since the FB node is high impedance, maintain the trace thickness small. The traces from RSET should be routed away from the body of the MagI³C power module to minimize noise pickup. Connect the feedback trace at the positive terminal of the last output capacitor (C OUT2). As this is the node of lowest noise.
