Since the parasitic inductance between each chip is extremely small, the module is highly suitable for use in buck converters to be operated at high frequencies. The control timing between the high-side MOS FET, low-side MOS FET, and driver is optimized so that high efficiency can be obtained at low output-voltage. Driver The driver has two types of power-supply voltage input pin, VCIN and VLDRV. VCIN supplies the operating voltage to the internal logic circuit. The low-side driving voltage is applied to VLDRV, so setting of the gate-driving voltage for the low-side MOS FET is independent of the voltage on VCIN. The VLDRV setting voltage is from 5 V to 16 V. The VCIN pin is connected to the UVL (under-voltage lockout) module, so that the driver is disabled as long as VCIN is 7.4 V or less. On cancellation of UVL, the driver remains enabled until the UVL input is driven to 7.0 V or less. The signal on pin DISBL# also enables or disables the circuit. When UVL disables the circuit, the built-in 5 V regulator does not operate, but when the signal on DISBL# disables the circuit, only output-pulse generation is terminated, and the 5 V regulator is not disabled. VCIN L H H H VLDRV >5V >5V >5V >5V DISBL#  L H Open Reg5V 0 5V 5V 5V Driver State Disable (GL, GH = L) Disable (GL, GH = L) Active Disable (GL, GH = L) Voltages from –0.3 V to VCIN can be applied to the DISBL# pin, so on/off control by a logic IC or the use of a resistor, etc., to pull the DISBL# line up to VCIN are both possible. The built-in 5 V regulator is a series regulator with temperature compensation. The voltage output by this regulator determines the operating voltage of the internal logic and gate-voltage swing for the high-side MOS FET. A ceramic capacitor with a value of 0.1 F or more must be connected between the CGND plane and the Reg5V pin. The PWM pin is the signal input pin for the driver chip. The input-voltage range is –0.3 V to (Reg5V + 3 V). When the PWM input is high, the gate of the high-side MOS FET (GH) is high and the gate of the low-side MOS FET (GL) is low. PWM L H GH L H GL H L REJ03G1480-0500 Rev.5.00 Mar 12, 2010 Page 10 of 14 R2J20602NP The PWM input is TTL level and has hysteresis. When the PWM input signal is abnormal, e.g., when the signal route from the control IC is abnormal, the tri-state function turns off the high- and low-side MOS FETs. This function operates when the PWM input signal stays in the input hysteresis window for 240 ns (typ.). After the tri-state mode has been entered and GH and GL have become low, a PWM input voltage of 4.0 V or more is required to make the circuit return to normal operation. 240 ns(tHOLD-OFF) 240 ns(tHOLD-OFF) PWM 4.0 V 1.2 V GH GL 240 ns(tHOLD-OFF) 240 ns(tHOLD-OFF) PWM 4.0 V 1.2 V GH GL Figure 1 For the high-side driver, the BOOT pin is the power-supply voltage pin and voltage VSWH provides a standard for operation of the high-side driving circuit. Consequently, the difference between the voltage on the BOOT and VSWH pins becomes the gate swing for the high-side MOS FET. Connect a bootstrap capacitor between the BOOT pin and the VSWH pin. Since the Schottky barrier diode (SBD) is connected between the BOOT and Reg5V pins, this bootstrap capacitor is charged up to 5 V. When the high-side MOS FET is turned on, voltage VSWH becomes equal to VIN, so VBOOT is boosted to VSWH + 5 V. The GH and GL pins are the gate-monitor pins for each MOS FET. MOS FETs The MOS FETs incorporated in R2J20602NP are highly suitable for synchronous-rectification buck conversion. For the high-side MOS FET, the drain is connected to the VIN pin and the source is connected to the VSWH pin. For the low-side MOS FET, the drain is connected to the VSWH pin and the source is connected to the PGND pin. REJ03G1480-0500 Rev.5.00 Mar 12, 2010 Page 11 of 14 R2J20602NP PCB Layout Example Figure 2 shows an example of a PCB layout for the R2J20602NP in application. The several ceramic capacitors (e.g. 10 F) close to VIN and PGND can be expected to decrease switching noise and improve efficiency. In that case, all sections of the GND pattern must be connected with other PCB layers via low impedances. Moreover, the wide VSWH pattern can be expected to have the effect of dissipating heat from the low-side MOS FET. When R2J20602NP is mounted on small circuit boards, such as those for point-of-load (POL) applications, heating of the device can be alleviated by adding thermal via-holes under the VIN and VSWH pads. 10 µF Vin 10 µF 10 µF GND 10 µF GND BOOT 1 µF VCIN 1 µF VLDRV Reg. 5 V VSWH GND PWM DISBL# 1 µF 0.1 µF GND To inductor To BOOT Via hole Figure 2 R2J20602NP PCB Layout Example (Top View) REJ03G1480-0500 Rev.5.00 Mar 12, 2010 Page 12 of 14 R2J20602NP Footprint Example (Unit: mm) 4.30 3.60 3.10 0.45 0.90 3.10 56 1 3.10 3.10 3.60 0.85 0.50 0.5 Figure 3 Footprint Example REJ03G1480-0500 Rev.5.00 Mar 12, 2010 Page 13 of 14 4.30 0.3 R2J20602NP Package Dimensions JEITA Package Code P-HVQFN56-8x8-0.50 RENESAS Code PVQN0056KA-A Previous Code — MASS[Typ.] 0.2g HD D 42 43 29 28 28 29 42 43 3.0 HE e 0.0 0.3 1.0 E Lp C 4 0. 3.0 Reference Symbol Dimension in Millimeters 1 Index mark 14 ZD ZE 56 15 15 14 1 b b1 56 y Min Nom Max D 7.95 8.00 8.05 E 7.95 8.00 8.05 A2 A 0.95 A1 0.005 b 0.20 0.25 0.30 b1 0.23 e 0.50 Lp 0.40 0.50 0.60 x y 0.05 y1 t HD 8.10 8.20 8.30 HE 8.10 8.20 8.30 ZD 0.75 ZE 0.75 c 0.17 0.22 0.27 c1 0.20 3.0 0.0 0.4 1.0 c1 c Ordering Information Part Name R2J20602NP#G3 Quantity 2500 pcs Shipping Container Taping Reel REJ03G1480-0500 Rev.5.00 Mar 12, 2010 Page 14 of 14 A1 A 3.0 Sales Strategic Planning Div.

You should use the products described herein within the range specified by Renesas, especially with respect to the maximum rating, operating supply voltage range, movement power voltage range, heat radiation characteristics, installation and other product characteristics. Renesas shall have no liability for malfunctions or damages arising out of the use of Renesas products beyond such specified ranges. 10. Although Renesas endeavors to improve the quality and reliability of its products, IC products have specific characteristics such as the occurrence of failure at a certain rate and malfunctions under certain use conditions. Please be sure to implement safety measures to guard against the possibility of physical injury, and injury or damage caused by fire in the event of the failure of a Renesas product, such as safety design for hardware and software including but not limited to redundancy, fire control and malfunction prevention, appropriate treatment for aging degradation or any other applicable measures. Among others, since the evaluation of microcomputer software alone is very difficult, please evaluate the safety of the final products or system manufactured by you. 11. In case Renesas products listed in this document are detached from the products to which the Renesas products are attached or affixed, the risk of accident such as swallowing by infants and small children is very high. You should implement safety measures so that Renesas products may not be easily detached from your products. Renesas shall have no liability for damages arising out of such detachment. 12. This document may not be reproduced or duplicated, in any form, in whole or in part, without prior written approval from Renesas. 13.
