PIN DESCRIPTIONS
FIGURE 3-1:
MIC45205 Pin Configuration.
The descriptions of the pins are listed in Table 3-1.
TABLE 3-1:
PIN FUNCTION TABLE
Pin Number
Pin Name
Description
1
GND
Analog Ground. Connect bottom feedback resistor to GND. GND and PGND are
internally connected.
2, 3
5VDD
Internal +5V Linear Regulator Output. Powered by VIN, 5VDD is the internal supply
bus for the device. In the applications with VIN < +5.5V, 5VDD should be tied to VIN to
bypass the linear regulator.
4, 5
PVDD
PVDD. Supply input for the internal low-side power MOSFET driver.
6, 7, 8, 45, 52
PGND
Power Ground. PGND is the return path for the step-down power module power
stage. The PGND pin connects to the sources of internal low-side power MOSFET,
the negative terminals of input capacitors, and the negative terminals of output
capacitors.
10, 11, 12, 31,
32, 33, 34
SW
The SW pin connects directly to the switch node. Due to the high-speed switching on
this pin, the SW pin should be routed away from sensitive nodes. The SW pin also
senses the current by monitoring the voltage across the low-side MOSFET during
OFF time.
14, 15, 16, 17,
18, 19
PVIN
Power Input Voltage. Connection to the drain of the internal high-side power
MOSFET. Connect an input capacitor from PVIN to PGND.
21, 22, 23, 24,
25, 26, 27, 28,
29
VOUT
Output Voltage. Connected to the internal inductor, the output capacitor should be
connected from this pin to PGND as close to the module as possible.
36, 37, 38
RIA
Ripple Injection Pin A. Leave floating, no connection.
