MAX15157BATJ+

DC DC Switching Controllers Overview

The MAX15157BATJ+T is a four-switch buck-boost controller from the MAX15157 family, designed for high-efficiency power conversion. It operates with an input voltage range of 8V to 60V and supports output voltages from 3V to 56V. The device features a switch frequency range of 120kHz to 1MHz, which can be set via external resistors or synchronized to an external clock. It utilizes a half-bridge buck configuration to drive two external MOSFETs and includes an internal LDO for bias generation. The controller offers adjustable slope compensation, current monitoring via an analog output, and comprehensive fault protection including overcurrent, overvoltage, and thermal shutdown.

DC DC Switching Controllers Feature Summary

• Supports modular design through dynamic output voltage setting via a 1V to 2.2V reference input
• Provides flexible switching frequency control with external resistor programming or clock synchronization capabilities
• Integrates precise current sensing with an analog monitor output for real-time feedback
• Includes robust fault protection mechanisms such as average and cycle-by-cycle overcurrent protection

DC DC Switching Controllers Applications

• Automotive power systems
• Telecommunications infrastructure
• Industrial equipment power supplies

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the component status as limited supply or obsolete if necessary. Ensure compatibility with the 32-pin TQFN package dimensions. Check RoHS compliance documentation for environmental requirements. Validate that the operating temperature range meets system specifications.

DC DC Switching Controllers Selection Notes

Select this controller for applications requiring wide input and output voltage ranges in a compact form factor. Consider the integrated bias LDO to reduce external component count. Evaluate the need for multi-phase operation if higher current delivery is required. Assess the benefit of clock synchronization for noise management in dense designs. Verify that the fault protection features align with system safety requirements.
