The featured is a compact, high-efficient DC-to-DC controller that includes an error amplifier, oscillator, PWM comparator, skip cycle comparator, voltage reference, soft-start, and high-speed lower ON-resistance driver for driving external power devices (NMOS or NPN). Additionally, a chip enable function is embedded to reduce power consumption after being shut down.

• Automatically goes into skip switching cycles under light load condition to maintain high efficiency.
• Durable construction.
