3A, 4.5A, 5.5A PWM STEP-UP DC-DC CONVERTER
Description
The PAM242x devices are high-performance, fixed frequency,
current-mode PWM step-up DC/DC converters that incorporate
internal power MOSFETs. The PAM242x includes an integrated
power MOSFET that supports peak currents of up to 3A/4.5A/5.5A.
The PAM242x utilizes simple external loop compensation allowing
optimization between component size, cost and AC performance
across a wide range of applications. Additional functions include an
externally programmable soft-start function for easy inrush current
control, internal over-voltage protection (OVP), cycle-by-cycle current
limit protection, under voltage lock-out and thermal shutdown.
The PAM242x is available in the small SOP-8(EP) package.

1 PGND
Power Ground
2 IN
Supply Input
3 EN
Enable Control. Connect to a logic high level to enable the IC. Connect to a logic low
level to disable the IC. When unused, connect EN pin to IN (do not leave pin floating).
4 COMP
Error Amplifier Compensation Node
5 AGND
Analog Ground
6 FB
Feedback Input.Connect this pin a resistor divider from the output to set the output
voltage. FB is regulated to 1.262V.
7 SS
Soft Start Control Input. Connect a capacitor from this pin to Ground to set soft-start
timing duration. SS is discharged to ground in shutdown. SS may be left unconnected if
soft start is not desired.
8 SW
Switch Output. Connect this pin to the inductor and the schottky diode. To minimize
EMI, minimize the PCB trace path between this pin and the input bypass capacitor.
