Leading edge pulse width modula- tion is used with the CS5101. The CS5101 is designed to operate over an 8V to 45V supply voltage (VCC) range and up to a 75V drive voltage (VC). The CS5101 features include a totem pole output with 1.5A peak output current capability, externally pro- grammable overcurrent protection, an on chip 2% precision 5V refer- ence, internally compensated error amplifier, externally synchronized switching frequency, and a power switch drain voltage monitor. It is available in a 14 lead plastic DIP or a 16 lead wide body SO package.
