ORDERING NUMBERS : L4962/A (12 + 2 + 2 Powerdip)
L4962E/A (Heptawatt
Vertical)
L4962EH/A (Horizontal
Heptawatt)
The L4962 is mounted in a 16-lead Powerdip plastic
package and Heptawatt package and requires very
few external components.
Efficient operation at switching frequencies up to
150KHz allows a reduction in the size and cost of
external filter components.
