This is a simple test board using the TPS61202 chip to create a more stable 5V power supply for the Game Boy Color. Also included are locations for the original 3.3V regulator and a replacement TPS62203 buck converter, in order to compare power consumption between the two chips. I also included a region at the top of the board for a TPS61202 breakout for breadboarding.
The enable pin on the left goes to the PS and EN pins of the 61202. The UVLO is programmed to turn off when VCC input is less than 1.8V with the parts list below.
U1: TPS61202
U2: TPS62203
U3: RN5RT33A (GBC 3.3V regulator)
R1 = R3 = 10kΩ
R2 = 61.9kΩ
C1 = C5 = C6 = C10 = 10uF
C3 = C7 = 0.1uF
C4 = C8 = 1uF
C9 = 4.7uF
