Figure15. 13W multiple power supply using FSDL0165RN
Multiple Output, 13W, 85-265VAC Input Power supply:
Figure 15 shows a multiple output supply typical for high
end set-top boxes containing high capacity hard disks for
recording. The supply delivers an output power of 13W
cont./15W peak (thermally limited) from an input voltage of
85 to 265 VAC. Efficiency at 9W, 85VAC is
≥
75%.
The 3.3 V and 5 V outputs are regulated to ±5% without the
need for secondary linear regulators. DC stacking (the sec-
ondary winding reference for the other output voltages is
connected to the anode of D15. For more accuracy, connec-
tion to the cathode of D15 will be better.) is used to minimize
the voltage error for the higher voltage outputs. Due to the
high ambient operating temperature requirement typical of a
set-top box (60
°
C) the FSDL0165RN is used to reduce con-
duction losses without a heatsink. Resistor R5 sets the device
current limit to limit overload power.
Leakage inductance clamping is provided by R1 and C8,
keeping the DRAIN voltage below 650 V under all condi-
tions. Resistor R1 and capacitor C8 are selected such that R1
dissipates power to prevent rising of DRAIN Voltage caused
by leakage inductance. The frequency modulation feature of
FSDL0165RN allows the circuit shown to meet CISPR2AB
with simple EMI filtering (C1, LF1 and C2) and the output
grounded. The secondaries are rectified and smoothed by
D12, D13, D14,and D15. Diode D15 for the 3.4V output is a
Schottky diode to maximize efficiency. Diode D14 for the 5
V output is a PN type to center the 5 V output at 5 V. The 3.3
V and 5 V output voltage require two capacitors in parallel to
meet the ripple current requirement. Switching noise filter-
ing is provided by L3, L2 and L1. Resistor R15 prevents
peak charging of the lightly loaded 23V output. The outputs
are regulated by the reference (TL431) voltage in secondary.
Both the 3.3 V and 5 V outputs are sensed via R13 and R14.
Resistor R22 provides bias for TL431and R21 sets the over-
all DC gain. Resistor R21, C209, R14 and R13 provide loop
compensation.
