2. PAM2804 General Description
The PAM2421 devices are high-performance, fixed frequency, current-mode PWM step-up DC/DC
converter that incorporate internal power MOSFET. The PAM2421 includes an integrated power
MOSFET that supports peak currents of up to 3A.
The PAM2421 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 PAM2421 is available in the small SOP-8(EP) package.
