PAM2421/ PAM2422/ PAM2423
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 SO-8EP package.
