Pin Description
Pin Number
MIC38300HYHL
Pin Name
Pin Name
1, 2, 3, 4, 5
SWO
Switch (Output): This is the output of the PFM Switcher.
6, 23, 24, 25,
26, 27, 28
SW
Switch Node: Floating for typical applications. Attach external resistor from
LPF to increase hysteretic frequency.
7, 22
ePAD
Exposed heat-sink pad. Recommend to connect to PGND.
8
AVIN
Analog Supply Voltage: Supply for the analog control circuitry. Requires
bypass capacitor to ground.
9
LPF
Low Pass Filter: Floating for typical applications. Attach external resistor
from SW to increase hysteretic frequency.
10
AGND
Analog Ground.
11
FB
Feedback: Input to the error amplifier. Connect to the external resistor
divider network to set the output voltage.
12, 13
LDOOUT
LDO Output (Output): Output of voltage regulator. Place capacitor to ground
to bypass the output voltage. Nominal bypass capacitor is 10μF.
14, 15
LDOIN
LDO Input: Connect to SW output. Requires a bypass capacitor to ground.
16, 17
PVIN
Input Supply Voltage (Input): Requires bypass capacitor to GND.
18
EN
Enable (Input): Logic low will shut down the device, reducing the quiescent
current to less than 50μA. This pin can also be used as an under-voltage
lockout function by connecting a resistor divider from EN/UVLO pin to VIN
and GND.
19, 20, 21
PGND
Power Ground.
