5 / 17 page SM8172A SEIKO NPC CORPORATION —5 11-3. DC/DC Converter VIN1 = VIN2 = 5.0V, GND = PGND = 0V, Ta = 25 °C unless otherwise noted. Parameter Pin Symbol Condition Rating Unit min typ max Current consumption 1 VIN1, 2 IDD1 No load, switching stopped – 0.35 0.75 mA Current consumption 2 VIN1, 2 IDD2 FB = VIN1, LX = Open – 2.5 5.5 mA Soft start time*1*2 *1. The soft start time is the interval during which the output current is limited internally in the IC, and is different from the DC/DC converter output raise time. If the maximum load current is output after soft start time startup, the output voltage does not fall. But, if the maximum load current is output before soft start time startup, it should be careful that the output voltage may fall. The LX starts the switching operation after 42 µs from ENDCO rising. After switching operation startup, the output current limit operates like linear increase (load current = 0A). The DC/DC converter output voltage rise time varies with the load current, output capacitance, and other conditions. –tSS 0.2 0.6 1.0 ms Output voltage range*2 –VDCO 0.8 – 1.8 V FB voltage FB VFB 0.588 0.6 0.612 V Maximum output current*2*3 –IDCO 900 – – mA Switching frequency LX fOSC 1.7 2.0 2.3 MHz Supply-side switch ON resistance LX RONP IDCO = 50mA – 0.3 – Ω GND-side switch ON resistance LX RONN IDCO = –50mA – 0.3 – Ω LX leakage current LX ILEAKLX Standby mode, LX = 1/2VIN –1.0 – 1.0 µA Overcurrent protection circuit operating current LX ILIMITLX Supply-side switch – 1.5 – A ENDCO Current limit 42 µsec (typ) High Low DCOUT 28 µsec (typ) 1.5A (typ) 1.8V 1.0V Soft start time LX switching start |
