Layout Consideration

For best performance, careful PCB layout is necessary.

Place all peripheral components as close to the IC as

possible. A short connection is highly recommended. The

following guidelines should be strictly followed when

designing a PCB layout for the RT9301.

1. All the traces of LED and VIN pin running from chip to

LEDs should be wide and short to reduce the parasitic

connection resistance.

2. Input capacitor (CIN) must be placed close to LEDs and

connected to ground plane. The anodes of LEDs must

be connected to CIN, not battery directly.

3. Current setting resistors RSET should be placed as close

to the chip as possible.

4. The GND should be connected to a strong ground plane

for heat sinking and noise protection.

5. The current setting resistors should be placed as close

to the IC as possible.

The maximum power dissipation depends on operating

ambient temperature for fixed TJ (MAX) and thermal resistance

θJA . For RT9301 packages, the Figure 6 of derating curves

allows the designer to see the effect of rising ambient

temperature on the maximum power allowed.
