LM43600PWPR General Description

The LM43600PWPR is a synchronous step-down DC-DC converter that combines efficiency, accuracy, and compactness in a single package. With a load current capability of up to 0.5 A and an input voltage range of 3.5 V to 36 V (42 V transient), this regulator is suitable for a wide range of power supply applications. Its peak current mode control allows for straightforward loop compensation and cycle-by-cycle current limiting, simplifying the design and optimization process for engineers. The LM43600 also features optional functions like programmable switching frequency, power-good flag, and thermal shutdown for added versatility and protection. Its pin-to-pin compatibility with other devices in the LM43600 family enables easy integration and design flexibility for different load current requirements

Key Features

Soft-Start Time Programmable by External Capacitor
Frequency Synch to External Clock for Multi-Phase Applications
Stable Output Voltage Tracking Capability
