Key Features
- Wide input voltage range of 9V to 46V with adjustable output from 5.1V to 40V covers a broad range of industrial and automotive supply rails
- 150kHz voltage-mode PWM buck controller enables compact external filter design with efficient step-down power conversion
- 7-pin HEPTAWATT through-hole package provides excellent thermal dissipation for high-current industrial power supply designs
Applications
The L4960H is designed for industrial power supplies, motor control pre-regulators, and embedded system power stages that require step-down regulation from unregulated or battery-derived DC inputs up to 46V. Its adjustable output range (5.1V to 40V) allows a single design to support multiple output voltage configurations by changing external resistors. The robust HEPTAWATT package and wide input range make it well-suited for harsh industrial environments with unstable supply conditions.

Frequently Asked Questions
What is the input and output voltage range of the L4960H?
The L4960H operates with an input voltage range of 9V to 46V (maximum 46V, nominal 35V) and provides an adjustable output voltage from 5.1V to 40V. This wide range allows the L4960H to serve as a step-down regulator for 12V, 24V, and 36V industrial supply buses.
What switching frequency does the L4960H use?
The L4960H operates at a switching frequency of 150kHz using voltage-mode pulse width modulation (PWM). This switching frequency balances inductor and capacitor size with efficiency, making it suitable for moderate-speed industrial power supply designs where component size and cost are important.
What package does the L4960H come in?
The L4960H comes in a 7-pin HEPTAWATT (H) through-hole package with JESD-30 code R-PZFM-T7. The HEPTAWATT package features a large metal tab for heatsink mounting, enabling efficient thermal management in high-power applications where the regulator dissipates significant heat at full load.
What control mode does the L4960H use and what are its advantages?
The L4960H uses voltage-mode PWM (pulse width modulation) control. Voltage-mode control offers simpler compensation network design and better noise immunity compared to current-mode, which is advantageous in industrial environments with electromagnetic interference. The single error amplifier feedback loop simplifies design verification and stability analysis.
