1. General Description

The RT4730 is a highly integrated power soluction with Buck-Boost, and inverting charge pump to generate positive and negative output voltage. The negative output voltages can be adjusted from -0.6V to -4V with 100mV steps. The positive output voltages can be adjusted from 2.8V to 4V with 100mV steps by SWIRE interface protocol. With its input voltage range of 2.9V to 5.2V, the RT4730 is optimized for products powered by single-cell battery and the output current up to 50mA.

2. Performance Sepcification Summary

3. Power-up & Measurement Procedure

1. Connect input power (2.9V < VIN < 5.2V) and input ground to VIN and GND test pins respectively. 2. Connect positive end and negative terminals of load to OVDD and OVSS and AVDD test pins respectively. 3. There is a 3-pin header “SWIRE” and “AVDD_EN” for enable control. To use a jumper at “H” option (upper side) to tie SWIRE test pin to input power VIN for enabling the device. Inversely, to use a jumper at “L” option to tie SWIRE test pin and ground GND for disabling the device. 4. Verify the output voltage (typically 6.6V) between OVDD and OVSS. 5. Connect an external load up to 50mA to the OVDD and OVSS and AVDD terminals and verify the output voltage and current.

4. OVDD and OVSS Output Voltage Setting

Set the negative output voltage with the Single Wire Protocal (SWIRE). Send the specified pulses to the header of SWIRE to program the OVDD and OVSS voltage. The output voltage is set by the following table:
