3 / 32 page Micrel, Inc. MIC22600 June 2011 3 M9999-062411-D Pin Description Pin Number MLF-24 Pin Number TSSOP-24 Pin Name Description 1, 6, 13, 18 3, 10, 15, 22 PVIN Power Supply Voltage (Input): Requires bypass capacitor to GND. 17 2 SVIN Signal Power Supply Voltage (Input): Requires bypass capacitor to GND. 2 11 EN/DLY EN/DLY (Input): When this pin is pulled higher than the enable threshold, the part will start up. Below this voltage the device is in its low quiescent current mode. The pin has a 1µA current source charging it to VIN. By adding a capacitor to this pin a delay may easily be generated. The enable function will not operate with an input voltage lower than the min specified voltage. 4 13 RC Ramp Control: Capacitor to ground from this pin determines slew rate of output voltage during start-up. This can be used for tracking capability as well as soft start. RC pin cannot be left floating. Use a minimum capacitor value of 220pF or larger. 14 23 FB Feedback: Input to the error amplifier, connect to the external resistor divider network to set the output voltage. 15 24 COMP Compensation pin (Input): Place a RC network to GND to compensate the device, see applications section. 5 14 POR/PG Power On Reset (Output): Open-drain output device indicates when the output is out of regulation and is active after the delay set by the DELAY pin. 7, 12, 19, 24 4, 9, 16, 21 PGND Power Ground (Signal): Ground 16 1 SGND Signal Ground (Signal): Ground 3 12 DELAY DELAY (Input): Capacitor to ground sets internal delay timer. Timer delays power-on reset (POR) output at turn-on and ramp down at turn-off. 8, 9, 10, 11, 20, 21, 22, 23 5, 6, 7, 8, 17, 18 19, 20 SW Switch (Output): Internal power MOSFET output switches. EP EP GND Exposed Pad (Power): Must make a full connection to a GND plane for full output power to be realized. |
