Any and all SANYO Semiconductor products described or contained herein do not have specifications
that can handle applications that require extremely high levels of reliability, such as life-support systems,
aircraft's control systems, or other applications whose failure can be reasonably expected to result in
serious physical and/or material damage. Consult with your SANYO Semiconductor representative
nearest you before usingany SANYO Semiconductor products described or contained herein in such
applications.
SANYO Semiconductor assumes no responsibility for equipment failures that result from using products
at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition
ranges, or other parameters) listed in products specifications of any and all SANYO Semiconductor

LV5040V
Overview
The LV5040V is a 2-channel step-down DC-DC converter controller IC.
Features
Provides dual step-down DC-DC converter controller circuits integrated on the same chip.
Provides an input UVLO circuit, an overcurrent detection function, an overtemperature detection function, soft start/soft
stop functions, and a startup delay circuit.
Output voltage monitoring functions (power good as well as OVP and UVP with timer latch functions)
Built-in cycle skip function that operates during rapid load changes
180° interleaved operation between phase 1 and phase 2 (supports multiphase drive in 2-phase parallel operation mode).
Supports synchronous operation between different devices (supports master/slave operation when multiple devices are
used).
