GENERAL DESCRIPTION
Dual 40V N-Channel synchronous MOSFET switches allow for low external component thus reducing complexity and minimizing board space. Through the use of a unique design the regulator does not rely on output capacitor ESR for stability, as do most other COT regulators. The operating frequency remains nearly constant with line and load variations due to the inverse relationship between the input voltage and the on-time. The oprating frequency can be externally programmed up to 1MHz. Protection features include VCC under-voltage lockout, thermal shutdown and gate drive under-voltage lockout. The part is available in a thermally enhanced eTSSOP-20 package FEATURES
