The RP604 is a buck-boost converter featuring a minimum supply current and a high efficiency at low-load. The device operates at the low operating quiescent current (IQ = 0.3 µA) to make the most of battery life for the battery driver operated intermittently.
|Input Voltage Range (Maximum Rating)||1.8 V to 5.5 V (6.5V)|
|Operating Quiescent Current (IQ)||0.3 µA|
|Standby Current||0.01 µA|
|Output Voltage Range||1.6 V to 5.2 V (0.1 V step)|
|Output Voltage Accuracy||±1.5%|
|Maximum Output Current||300 mA (at Buck)|
|Built-in Driver On-resistance (RP604Z, VIN = 3.6 V)||PMOS = Typ. 0.12 Ω, NMOS = Typ. 0.12 Ω|
|Protection Features||UVLO, OVP, Lx Peak Current, and Thermal Shutdown|

*) The tab on the bottom of the package shown by blue circle is a substrate potential (GND). It is recommended that this tab be connected to the ground plane on the board but it is possible to leave the tab floating.
PRODUCT LONGEVITY PROGRAM
RP604 series operate PRODUCT LONGEVITY PROGRAM.
This program has been introduced to help customers select the most appropriate part for applications that require long life cycles.
The set output voltage, the auto-discharge function and the package are user-selectable options.
|Product Name||Package||Quantity per Reel|
* Auto-discharge function quickly lowers the output voltage to 0 V, when the chip enable signal is switched from the active mode to the standby mode, by releasing the electrical charge accumulated in the external capacitor.
