MAX15157BATJ+T

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 features a half-bridge buck configuration driving two external MOSFETs and supports single-phase or multi-phase operation up to four phases. The device accepts an input voltage range of 8V to 60V and provides an adjustable output voltage range of 3V to 56V. Switching frequency is programmable from 120kHz to 1MHz via an external resistor or synchronized to an external clock. It operates within a junction temperature range of -40°C to +125°C and utilizes a 5mm x 5mm, 32-pin TQFN package.

DC DC Switching Controllers Feature Summary

• Dynamic output voltage setting through a 1V to 2.2V reference input (REFIN) enables modular design flexibility.
• Integrated fault protection mechanisms including average and cycle-by-cycle overcurrent protection, input undervoltage lockout, and thermal shutdown ensure system reliability.
• Supports clock synchronization and adjustable slope compensation for stable multi-phase operation.
• Includes an internal low-dropout regulator (LDO) for bias generation and an analog current monitor output (IMON).

DC DC Switching Controllers Procurement Notes

Verify the component authenticity by checking the manufacturer marking against official datasheet specifications. Confirm the specific suffix matches the required package and temperature grade. Ensure the supplier provides valid traceability documentation. Cross-reference the ordering part number with the manufacturer's latest product status notifications to confirm availability and lifecycle stage before finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this controller when a wide input voltage range and flexible output configuration are required. Consider its capability for multi-phase operation if higher current delivery is needed. Evaluate the need for clock synchronization in noise-sensitive environments. Verify that the external component selection aligns with the specified switching frequency range and thermal requirements for the target application environment.
