The TLVM365R15 or TLVM365R1 is an easy-to-use, synchronous buck, DC/DC power module that operates from a 3-V to 65-V supply voltage. With an integrated power controller, inductor, and MOSFETs, the TLVM365R15 or TLVM365R1 delivers up to 150-mA or 100-mA DC load current with high efficiency and ultra-low input quiescent current in a very compact design size. The TLVM365R15 or TLVM365R1 can operate over a wide range of switching frequencies and duty ratios. If the minimum ON-time or OFF-time cannot support the desired duty ratio, the switching frequency is reduced automatically, maintaining the output voltage regulation. Although designed for simple implementation, this device offers flexibility to optimize the usage according to the target application.

The TLVM365R15 or TLVM365R1 module also includes inherent protection features for robust system requirements:

• An open-drain PGOOD indicator for power-rail sequencing and fault reporting
• Precision enable input with hysteresis, providing:
  • Programmable line undervoltage lockout (UVLO)
  • Remote ON and OFF capability
• Internally fixed output-voltage soft start with monotonic start-up into prebiased loads
• Current limiting implemented by cycle-by-cycle peak and valley current limits
• Thermal shutdown with automatic recovery

These features enable a flexible and easy-to-use platform for a wide range of applications. The pin arrangement is designed for a simple layout, requiring few external components. See Layout for a layout example.

The TLVM365R15 or TLVM365R1 incorporates specific features to improve EMI performance in noise-sensitive applications:

• An optimized package that incorporates flip chip on lead (FCOL) technology and pinout design which enables a shielded switch-node layout that mitigates radiated EMI
• A programmable switching frequency from 200 kHz to 2.2 MHz enables optimization of external passives and promotes the avoidance of noise sensitive bands
