LV5061V-TLM-H

DC DC Switching Controllers Overview

The LV5061V-TLM-H is a single-channel step-down switching regulator controller manufactured by Sanyo Semicon Device. It features a low operation current of approximately 90μA in light load mode, ensuring high efficiency and reduced power consumption. The device incorporates an overcurrent protection (OCP) circuit using a P-by-P method, which can shift to HICCUP operation or latch-off if connected to the GND pin. The oscillation frequency is adjustable via an external pin, ranging from 300 kHz to 2.2 MHz. Built-in protections include Under Voltage Lock Out (UVLO) and Thermal Shutdown (TSD).

DC DC Switching Controllers Feature Summary

• Low power consumption with a maximum light load mode current of 90μA.
• Built-in overcurrent protection circuit with selectable HICCUP or latch-off behavior.
• Adjustable oscillation frequency set by external components.
• Integrated under voltage lock out and thermal shutdown functions.

DC DC Switching Controllers Applications

• Step-down switching regulator designs requiring low standby power.
• Battery-powered electronic devices needing efficient power management.
• General-purpose DC-DC converter applications with adjustable frequency.

DC DC Switching Controllers Procurement Notes

Verify the manufacturer designation as Sanyo Semicon Device or ON Semiconductor, as acquisition rights may have transferred. Confirm the specific suffix -TLM-H corresponds to the required tape-and-reel packaging format for surface-mount assembly. Ensure compatibility with the intended PCB layout for the adjustable frequency and protection pins before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this component when a single-channel buck converter topology is required with minimal quiescent current. The adjustable frequency range allows optimization for size versus efficiency trade-offs. Consider the OCP configuration options if system-level fault handling requires either recovery or latching behavior. Verify that the external component values support the desired operating frequency within the specified 300 kHz to 2.2 MHz range.

DC DC Switching Controllers Part Context

The LV5061V series belongs to Sanyo's family of low-power switching regulator controllers designed for efficiency-critical applications. The -TLM-H variant specifically denotes the surface-mount package configuration suitable for automated assembly processes. This part complements other Sanyo power management ICs like the LV5068V, offering a specialized solution for single-output step-down conversion with integrated protection features.
