With simulated source impedance of
10uH, 5Hz to 20MHz. Use a 100uF/100V
electrolytic capacitor with ESR=1 ohm
max, at 200KHz@25°C.
CAUTION: This converter is not internally fused. An input line fuse must be used in application.
Recommend a fast-acting fuse with maximum rating of 4A@1.2Vout or 10A@3.3Vout on system
board. Refer to the fuse manufacture’s datasheet for further information.
Notes: 1. This converter has internal C-L-C (0.47uF-2.2uH-4.4uF) filter.
2. All specifications are typical at 25 C unless otherwise stated.
