Description
The R-5XXX series is a high performance 1.2V to 5.0V , 2Amp to 5Amp,12-Pin SIP (single in-line
package) integrated switching regulator (ISR). Synchronuous - rectified design yields excellent efficien-
cies up to 96%.Short circuit protection with crowbar function to reduce the short current under 50mA
of input current. Autosense function compensates for any losses in long circuit loops.

Parallel Application Circuit
The R-52xx, R-53xx, R-54xx series can be used in parallel to upgrade the output current capacity for
the same output voltage.
For example, the R-543.3PA can parallel up with another R-554.3PA to give up to 8 amps or with the
R-533.3PA or R-523.3PA types to give output currents of up to 7 Amps or 6 Amps.
The R-55xx series cannot be paralleled.

Output Current vs Input Voltage
How to calculating the max output current
The internal power dissipation(PD)follows the equation:
PD = Io × Vo × (1-η)
Io = PD / Vo × (1-η)
90
85
80
Where
PD = Internal power dissipation
Io = Output current
Vo = Output voltage
η = Efficiency
60
40
20
Example: R-545.0P , at Vin = 18Vdc , Vo = 5Vdc ,η=93% (see table 1)
(a) When Ta = 60°C , PD = 1.4 Watt (see fig-1)
Io = 1.4(W) / 5(V) × (1-0.93) = 4(A)
(b) When Ta = 85°C , PD = 1 Watt (see fig-1)
Io = 1(W) / 5(V) × (1-0.93) = 2.857(A)

1.4
Internal Power Dissipation (W)
(c) At Vin = 12Vdc efficiency = 94% (see table 1)
When Ta = 85°C , PD = 1 Watt (see fig-1)
Io = 1(W) / 5(V) × (1-0.94) =3.33(A)
