RT9014/A Preliminary 2 DS9014/A-08 August 2007 www.richtek.com Functional Pin Description Pin No. RT9014-□□PQW RT9014A-□□ Pin Name Pin Function 1 1 VIN Supply Input. 2 -- EN Chip Enable (Active High). -- 2 EN1 Chip Enable 1 (Active High). -- 3 EN2 Chip Enable 2 (Active High). 3 -- NC No Internal Connection Pin. 4 4 SW Active high signal drives open-drain N-MOSFET. Note that this pin is high impedance. There should be a pull low 100k Ω resistor connected to GND when the control signal is floating. 5 5 SET Delay Set Input: Connect external capacitor to GND to set the internal delay for the POR output. When left open, there is no delay. This pin cannot be grounded. 6 6 GND Common Ground. 7 7 DRV Open-Drain Output: Capable of sinking 150mA. 8 8 POR Power-On Reset Output: Open-drain output. Active low indicates an output under-voltage condition on regulator 2. 9 9 VOUT2 Channel 2 Output Voltage 10 10 VOUT1 Channel 1 Output Voltage Exposed Pad (11) Exposed Pad (11) GND The exposed pad must be soldered to a large PCB and connected to GND for maximum power dissipation.
