LM26001 chip is a standby mode designed for high efficiency requirements of a switching regulator application. The device features low current sleep mode to maintain light load conditions and current mode control efficiency over a wide input voltage range. Quiescent current down to 10μA in typical shutdown mode and less than 40μA in sleep mode. Forced PWM mode can also be used to disable sleep mode.

LM26001 chip can provide up to a continuous load current limit with a fixed current of 1.5A via an internal N-channel switch. The device has a wide input voltage range of 4.0V to 38V and can operate input voltages at 3V low-line transients.

The operating frequency is adjustable from 150 kHz to 500 kHz and a resistor that can be synchronized to an external clock.

Other features include a good power supply, adjustable soft-start, allowable pins, input undervoltage protection, and an internal bootstrap diode to reduce the number of components.
