JW5033S

JW5033S 18V/2A Sync. Step-Down Converter Parameters Subject to Change Without Notice DESCRIPTION FEATURES The JW ®5033S is a current mode monolithic buck voltage converter. Operating with an input range of 3.7V-18V, the JW5033S delivers 2A of continuous output current with two integrated N-Channel MOSFETs. At light loads, regulators operate in low frequency to maintain high efficiency and low output ripple. The JW5033S guarantees robustness with short circuit protection, thermal protection, current run-away protection, and input under voltage lockout. The JW5033S is available in a 6-pin TSOT23-6 and SOT563 package, which provides a compact solution with minimal external components.

The JW5033S guarantees robust performance from -40°C to 150°C junction temperature. The junction temperature range specification is assured by design, characterization and correlation with statistical process controls. The JW5033S includes thermal protection that is intended to protect the device in overload conditions. Thermal protection is active when junction temperature exceeds the maximum operating junction temperature. Continuous operation over the specified absolute maximum operating junction temperature may damage the device. Measured on JESD51-7, 4-layer PCB JW5033S Rev.0.88 JoulWatt® Proprietary Information.
