DC DC Switching Controllers datasheet and documents for ISL6522CB-TR5190
DC DC Switching Controllers Overview
The ISL6522CB-TR5190 is a Buck and Synchronous Rectifier Pulse-Width Modulator (PWM) Controller manufactured by Intersil. It operates as a DC-DC switching controller with a positive output configuration. The device supports a switch frequency range of 50 kHz to 1 MHz and delivers an output current of 500 mA. It functions within an input supply voltage of 12 V, providing an adjustable output voltage from 800 mV to 12 V. The component is housed in a 14-SOIC package and is rated for operation between 0°C and +70°C.
DC DC Switching Controllers Feature Summary
- Integrates buck and synchronous rectifier PWM control for step-down power management
- Supports wide switching frequency adjustment from 50 kHz to 1 MHz
- Provides high drive capability with 500 mA output current
DC DC Switching Controllers Applications
- Buck regulator designs requiring synchronous rectification
- Positive output step-down DC-DC converter circuits
- General power management integrated circuit applications
DC DC Switching Controllers Procurement Notes
Verify the specific suffix -TR5190 against official Intersil documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with existing board layouts for the 14-SOIC footprint. Confirm that the commercial temperature range meets system requirements before procurement.
DC DC Switching Controllers Selection Notes
Select this component when a dedicated synchronous buck controller is required rather than an integrated power stage. Consider the 14-SOIC package size for space-constrained designs. Verify that the external MOSFET selection aligns with the 500 mA driver capability and the desired switching frequency range.
DC DC Switching Controllers Part Context
This part belongs to the ISL6522 series of switching controllers. It serves as a specialized solution for efficient power conversion, distinct from standard non-synchronous controllers. The device complements other PMIC offerings by providing precise duty cycle control for high-efficiency step-down topologies.
