• Single input dual output (ch1: 5V/0.4A, ch2: 3.3V/0.2A)
• Power on reset function
• Watchdog timer
• Built-in drooping type overcurrent and thermal protection circuits (ch1) Dropper Type System Regulator ICs [Surface-mount 2-output] SPF3004 Notes: *3: Refer to dropout voltage. *4: Since P D(max) = {(VIN– VO1) • (IO1+ IO2)} + (VIN • Iq) + {(VO1– VO2) • IO2}= 30W , VIN(max), IO1(max) and IO2(max) may be limited depending on operating conditions. *5: The Vo1-fail and RESET terminals are pulled up in the IC; may be directly connected to logic circuits. *6: The thermal protection function is built in V O1 (CH1 side) only. The design thermal protection starting temperature is 155 °C (min.) and 165°C (typ). These values represent the design warranty. *7: The threshold voltage at the W/D/C terminals is determined by the presence/absence of WD operation (occurrence of RESET signal pulses). The W/D/C function is assumed to be OFF during the period when RESET pulses occur. *8: The TOFF-EN operation (VEN: 5V 0V) for Tj=150°C is 16mS (0.32V/mS) max.
