IS32PM3420B
DESCRIPTION
The IS32PM3420B regulator is an easy-to-use synchronous step-down DC-DC converter capable of driving up to 3A of load current from an input voltage ranging of 3.8V to 36V. The IS32PM3420B provides exceptional efficiency, output accuracy and drop-out voltage in a very small solution size. Constant on-time control mode is employed to achieve simple controlloop pensation and fast transient response. The IS32PM3420B supports both Forced Continuous Conduction Mode (FCCM) and Pulse Frequency Modulation mode (PFM) at light-load condition, which is selected by the FPWM pin. It requires few external ponents. Pin arrangement allows simple, optimum PCB layout. Protection features include thermal shutdown, VDD under-voltage lockout, cycleby-cycle current limit, over-voltage and output shortcircuit protection.
The IS32PM3420B device is available in the SOP-8EP package with an exposed pad for enhanced thermal dissipation.
