RP6003
2A, 24V, Synchronous Step-Down Converter
General Description
The RP6003 is a high-efficiency, monolithic synchronous
step-down DC/DC converter that can deliver up to 2A output
current from a 4.5V to 24V input supply. The RP6003's
current mode architecture and external compensation
allow the transient response to be optimized over a wide
range of loads and output capacitors.
The IC Provides cycle-by-cycle current limit protection
against shorted outputs and soft-start eliminates input
current surge during start-up. Fault conditions also include
output under voltage protection and thermal shutdown.
The low current (<3µA) shutdown mode provides output
disconnect, enabling easy power management in battery-
powered systems. The RP6003 is available in HDIP-12
and SOP-8(Exposed Pad) packages.

Note 1. Stresses listed as the above "Absolute Maximum Ratings" may cause permanent damage to the device. These are for
stress ratings. Functional operation of the device at these or any other conditions beyond those indicated in the
operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended
periods may remain possibility to affect device reliability.
Note 2. Devices are ESD sensitive. Handling precaution is recommended.
Note 3. The device is not guaranteed to function outside its operating conditions.
Note 4. θJA is measured in the natural convection at TA = 25°C on a high effective four layers thermal conductivity test board of
JEDEC 51-7 thermal measurement standard. The case point of θJC is on the exposed pad for SOP-8 (Exposed Pad)
package, on the central lead of the HDIP-12 package. The PCB copper area of the HDIP-12 is about 300m2 connected
with the HDIP-12 exposed lead.
