Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix PWP corresponds to the 16-PowerTSSOP package configuration. Confirm RoHS3 compliance status as per the latest manufacturer documentation. Ensure ESD handling protocols are followed during assembly due to surface mount sensitivity. Cross-reference the datasheet revision date to validate thermal characteristics and pinout definitions before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a single-output buck converter with 1A capacity is required within a 36V input limit. Compare against the LM43600 series if lower current (500mA) suffices, or the LM43602 series for higher current (2A) needs. Consider the fixed switching frequency constraints versus variable frequency alternatives for noise-sensitive applications. Evaluate board space requirements against the PowerTSSOP footprint dimensions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the Simple Switcher family of power management ICs designed for ease of use and robust performance. It complements other regulators like the LM46000 series which offers wider input voltage ranges up to 60V. The LM43601 serves as a mid-range solution bridging lower current shunt references and higher power automotive-grade converters.
