RP605x Series 300mA Ultra-low Power Buck Boost DC/DC Converter with Battery Monitor No. EA-516-210611 OVERVIEW RP605x is an ultra-low power DC/DC converter with a Battery Monitor (BM). The battery monitor divides the input voltage (VIN) into 1/3 or 1/4 and directly provides the buffered voltage to a low-voltage AD converter in MCU, it monitors the remaining quantity of the battery. KEY BENEFITS Long-time operation of battery powered equipment and downsizing of battery due to the ultra-low consumption current (IQ = 0.3 A). Reducing components and saving space by combining DC/DC and BM into a single chip. Suitable for coin batteries and USB ports due to its wide input voltage range from 1.8 V to 5.5 V KEY SPECIFICATIONS PACKAGES (unit: mm) DC/DC Section Supply Current: Typ. 0.3 A Output Current: 300 mA Input Voltage Range: 1.8 V to 5.5 V Output Voltage Range: 1.6 V to 5.2 V Output Voltage Accuracy: 1.5% Battery Monitor Section Output Voltage: V /3 (RP605xxx3x) WLCSP-20-P3 IN DFN(PLP)2730-12 VIN/4 (RP605xxx4x) 2.315 x 1.71 x 0.36 3.00 x 2.70 x 0.6 Supply Current: Typ. 0.1 A TYPICAL APPLICATIONS RP605x CE1 BULX Signal MCU L PVIN BOLX VIN 2.2H Buck-Boost VFB VOUT VOUT DC/DC Converter VCC PGND C OUT1 22F AVIN AGND Battery Monitor CE2 BM V BM Signal ADC C IN C OUT2 10F 0.1F to 0.22F APPLICATIONS Devices with Coin Cell Battery and Lithium Ion Battery Wearable devises including Smart watch, Smart band, and Health monitor Low power RF Modules including: Bluetooth LE, Zigbee, WiSun and ANT Low power CPUs, Memory, Sensor device and Energy harvester 1 RP605x No. EA-516-210611 SELECTION GUIDE (1) The DC/DC set output voltage, the division ratio of BM output, the DC/DC auto-discharge function , and the package are user-selectable options. Selection Guide Product Name Package Quantity per Reel Pb Free Halogen Free RP605Zxx -E2-F WLCSP-20-P3 5,000 pcs Yes Yes RP605Kxx -TR DFN(PLP)2730-12 5,000 pcs Yes Yes xx: Specify the DC/DC set output voltage (VSET) Fixed output voltage type: 1.6 V (16) to 5.2 V (52) in 0.1 V step Refer to the Product-specific Electrical Characteristics for detail information : Specify the division ratio of BM output 3 V /3 IN 4 VIN/4 : Specify the DC/DC auto-discharge option. A: DC/DC auto-discharge is not included B: DC/DC auto-discharge is included (1) Auto-discharge function quickly lowers the output voltage to 0 V by releasing the electrical charge accumulated in the external capacitor when the chip enable signal is switched from the active mode to the standby mode. 2
