8 / 33 page NN30320A Page 8 of 32 Product Standards PIN CONFIGURATION Top View Pin No. Pin name Type Description 1 LX Output Power MOSFET output pin An inductor is connected and switching operation is carried out between V IN and GND. Due to high current and large amplitude at this terminal, the parasitic inductance and impedance of the routing path can cause an increase in noise and a degradation in the efficiency. Routing path should be kept as short as possible. 2 3 4 5 6 7 PGND Ground Ground pin for Power MOSFET 8 9 10 MODE Input Skip (discontinuous) mode / FCCM (Forced Continuous Conduction Mode ) select pin Skip mode is set at Low level input, FCCM is set at High level input. 11 AGND Ground Ground pin 20 12 AVIN Power supply Power supply pin Recommended rise time ( time to reach 90 % of set value ) setting is greater than or equal to 10 µs and less than or equal to 1 s. 13 FSEL Input Frequency selection pin This is set to 430 kHz at Low level input, 210 kHz at High level input, and 650 kHz at open. 14 EN Input ON / OFF control pin DC-DC is stopped at Low level input, and it is started at High level input. PIN FUNCTIONS Note : Detailed pin descriptions are provided in the OPERATION and APPLICATION INFORMATION section.
