When the voltage on the OVP pin rises inputs, raise up to replace the output voltage of error amplifier until the ramp voltage reaches the VCOMP. above the OVP threshold (28V typical), the converter stops switching and prevents the output voltage from rising. Current-Limit Protection The converter can work again when the falling OVP voltage falls below the OVP voltage threshold. The APW7207 monitors the inductor current, flowing through the N-channel MOSFET, and limits the current peak at current-limit level to prevent loads and the APW7207 from damages during overload or short-circuit conditions.

A.2 - Dec., 2009 8 www.anpec.com.tw APW7207 Application Information The peak inductor current is calculated as the following equation: Input Capacitor Selection The input capacitor (CIN) reduces the ripple of the input current drawn from the input supply and reduces noise injection into the IC. The reflected ripple voltage will be smaller when an input capacitor with larger capacitance is used. For reliable operation, it is recommended to select the capacitor with maximum voltage rating at least IPEAK = IIN(MAX ) + VIN 1.2 times of the maximum input voltage. The capacitors should be placed close to the VIN and GND. 1 VIN ⋅ (VOUT − VIN ) ⋅ 2 VOUT ⋅ L ⋅ FSW IL IIN LX N-FET CIN IOUT D1 VOUT ESR ISW COUT Inductor Selection Selecting an inductor with low dc resistance reduces con- IL duction losses and achieves high efficiency.

Mainly, the inductor value deter- IIN mines the inductor ripple current: larger inductor value results in smaller inductor ripple current and lower con- ISW duction losses of the converter. However, larger inductor value generates slower load transient response. A reasonable design rule is to set the ripple current, ∆IL, to be 30% to 50% of the maximum average inductor current, IL(AVG).

The output ripple is the sum of the voltages across the ESR and the ideal η = Efficiency ∆IL /IL(AVG) = inductor ripple current/average current output capacitor. (0.3 to 0.5 typical) To avoid the saturation of the inductor, the inductor should be rated at least for the maximum input current of the Δ VOUT = ΔVESR + ΔVCOUT converter plus the inductor ripple current.

Layout Consideration For all switching power supplies, the layout is an important step in the design; especially at high peak currents and switching frequencies. If the layout is not carefully done, the regulator might show noise problems and duty cycle jitter. 1. The input capacitor should be placed close to the VIN and GND. Connecting the capacitor with VIN and GND pins by short and wide tracks without using any vias for filtering and minimizing the input voltage ripple. 2. The inductor should be placed as close as possible to the LX pin to minimize length of the copper tracks as well as the noise coupling into other circuits. 3. Since the feedback pin and network is a high impedance circuit, the feedback network should be routed away from the inductor. The feedback pin and feedback network should be shielded with a ground plane or track to minimize noise coupling into this circuit. 4. A star ground connection or ground plane minimizes ground shifts and noise is recommended.
