Pin Description (Continued)

Pin Number

Pin Name

Description

Compensation Pin (Input): The MIC22705 uses an internal compensation network containing a

fixed-frequency zero (phase lead response) and pole (phase lag response) which allows the

external compensation network to be much simplified for stability. The addition of a single

capacitor and resistor to the COMP pin will add the necessary pole and zero for voltage mode

loop stability using low-value, low-ESR ceramic capacitors.

COMP

SGND

SVIN

Signal Ground: Internal signal ground for all low power circuits.

Signal Power Supply Voltage (Input): This pin is connected externally to the PVIN pin. A 2.2µF

ceramic capacitor from the SVIN pin to SGND must be placed next to the IC.

Power Ground: Internal ground connection to the source of the internal N-Channel MOSFETs.

7, 12, 19, 24

PGND

Switch (Output): This is the connection to the drain of the internal P-Channel MOSFET and drain

of the N-Channel MOSFET. This is a high-frequency, high-power connection; therefore traces

should be kept as short and as wide as practical.

8, 9, 10, 11,

20, 21, 22, 23

GND

Exposed Pad (Power): Must be connected to the GND plane for full output power to be realized.
