RP605Z

RP605x Series 300mA Ultra-low Power Buck Boost DC/DC Converter with Battery Monitor No. EA-516-200226 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 µA). ● 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 DC/DC Section ● Supply Current: Typ. 0.3 μA ● 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: VIN/3 (RP605xxx3x) VIN/4 (RP605xxx4x) ● Supply Current: Typ. 0.1 μA PACKAGES (unit: mm) WLCSP-20-P3 2.315 x 1.71 x 0.36 DFN(PLP)2730-12 3.00 x 2.70 x 0.6 TYPICAL APPLICATIONS Signal VIN RP605x CE1 PVIN VFB AVIN Buck-Boost DC/DC Converter BULX BOLX VOUT PGND AGND L 2.2µH VOUT MCU VCC COUT1 22µF CE2 Signal CIN　　 ≥ 10µF Battery Monitor BM VBM ADC COUT2 0.1µF to 0.22µF APPLICATIONS Devices with Coin Cell Battery and Lithium Ion Battery Wearable devises including Smart watch, Smart band, and Health monitor Low p...
