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.
