Constant ONTIME and operating frequency ONTIME (Ton) can be determined by VIN input voltage and RT resistor. Ton = FB × 154pF × ( 1 / VIN ) × (RT + 5kΩ) + 10nsec Freq = VOUT / VIN × 1 / Ton ・FB : FB threshold voltage (0.765V, typ.). ・154pF, 5kΩ, 10nsec are constant values in the IC. ONTIME and Frequency are calculated as below when VIN=12V, VOUT=3.3V, RT=62kΩ. Ton = 0.750 [V] × 154p [F] × ( 1 / 12 [V] ) × ( 62k [Ω] + 5k [Ω]) + 10n [sec] =655n [sec] Freq = 3.3 [V] / 12 [V] × 1 / 655n [sec] =420k [Hz] ONTIME and frequency also depends on other conditions such as output current load. 2. Inductor (L) Selection ΔIL VIN The value of ΔIL is shown as formula below. The larger value of the inductance or the faster switching frequency make the lower ripple voltage. (VIN -VOUT)×VOUT [A] ΔIL = L×VIN×f The proper output ripple current setting is about 30% of maximum output current. HG IL ΔIL = 0.3×IOUTmax. [A] VOUT SW (VIN -VOUT)×VOUT L LG L= Co ΔIL×VIN×f [H] (ΔIL: Inductor ripple current, f:switching frequency Figure 16. Inductor Ripple Current ※A larger current than the inductor’s rated current will cause magnetic saturation in the inductor, and decrease efficiency. When selecting an inductor, be sure to allow enough margins to assure that peak current does not exceed the inductor’s rated current value. ※To minimize loss of inductor and improve efficiency, choose a inductor with a low resistance (DCR, ACR). www.rohm.com © 2013 ROHM Co., Ltd.

Output Capacitor (COUT) Selection VIN HG VOUT SW L ESR LG Load ESL Output Capacitor (COUT) has a considerable influence on output voltage regulation due to a rapid load change and smoothing output ripple voltage. Determine the capacitor by considering the value of capacity, the equivalent series resistance, and equivalent series inductance. Also, make sure the capacitor’s voltage rating is high enough for the set output voltage (including ripple). CEXT Output ripple voltage is determined as in formula below. COUT ΔVOUT=ΔIL/(8×COUT×f)+ESR×ΔIL +ESL×ΔIL / TON Figure 17. Output Capacitor (ESR: Equivalent series resistance、ESL: Equivalent series inductance) Also, give consideration to the conditions in formula below for output capacitance, bearing in mind that output rise time must be established within the fixed soft start time. As output capacitance, bypass capacitor will be also connected to output load side (CEXT, Figure 23). Please set the over current detection value with regards to these capacitance. Co+CEXT≦ Tss×(Limit-IOUT) VOUT Limit: OCP current limit IOUT: Output current Tss: soft start time Note: an improper output capacitor may cause startup malfunctions. 4. Input Capacitor (CIN) Selection VIN In order to prevent transient spikes in voltage, the input capacitor should have a low enough ESR resistance to fully support a large ripple current. The formula for ripple current IRMS is given as below. CIN HG VOUT SW L IRMS=IOUT× √VOUT (VIN -VOUT) [A] VIN Co LG Where VIN =2×VOUT, IRMS= IOUT 2 Figure 18. Input Capacitor A low ESR capacitor is recommended to reduce ESR loss and improve efficiency. www.rohm.com © 2013 ROHM Co., Ltd. All rights reserved.

So it needs external ripples to stabilize the system. The FB voltage ramp is expected around 50mV. The external ramp is generated through the circuit as follows. VOUT Rup SW Csw Rsw FB SW VOUT Rdown Vripple FB FB( DC) REF Figure 19. Ripple Injection Circuit The FB ramp follows: Vripple = (VIN – VOUT) × Ton / (Csw Rsw) (T < Csw Rup//Rdown Pin B, the PN junction operates as a parasitic transistor Parasitic diodes occur inevitably in the structure of the IC, and the operation of these parasitic diodes can result in mutual interference among circuits, operational faults, or physical damage. Accordingly, conditions that cause these diodes to operate, such as applying a voltage lower than the GND voltage to an input pin (and thus to the P substrate) should be avoided. www.rohm.com © 2013 ROHM Co., Ltd.

Example of IC structure (12) Ground Wiring Pattern When using both small-signal and large-current GND traces, the two ground traces should be routed separately but connected to a single ground potential within the application in order to avoid variations in the small-signal ground caused by large currents. Also ensure that the GND traces of external components do not cause variations on GND voltage. (13) Operating Condition The electrical characteristics indicated in this datasheet are not guaranteed for the whole operational and temperature ranges, however these characteristics do not significantly fluctuate within the operational and temperature ranges. (14) Thermal shutdown (TSD) circuit The IC incorporates a built-in thermal shutdown circuit, which is designed to turn the IC off completely in the event of thermal overload. It is not designed to protect the IC from damage or guarantee its operation. ICs should not be used after this function has activated, or in applications where the operation of this circuit is assumed. If the thermal shutdown is activated while the load current exists, the output may possibly be latched off at the release of the thermal shutdown. TSD ON Temp.[℃] 175 (typ.)
