LM26001MXA/NOPB

TEXAS INSTRUMENTS  LM26001MXA/NOPB.  芯片, 开关稳压器, 16-TSSOP

The is a Switching Regulator designed for the high-efficiency requirements of applications with standby modes. The device features a low-current sleep mode to maintain efficiency under light-load conditions and current-mode control for accurate regulation over a wide input voltage range. Quiescent current is reduced to 10µA typically in shutdown mode and less than 40µA in sleep mode. Forced PWM mode is also available to disable sleep mode. The LM26001 can deliver up to 1.5A of continuous load current with a fixed current limit, through the internal N-channel switch. The part has a wide input voltage range of 4 to 38V and can operate with input voltages as low as 3V during line transients. Operating frequency is adjustable from 150 to 500kHz with a single resistor and can be synchronized to an external clock. Other features include power good, adjustable soft-start, enable pin, input undervoltage protection and an internal bootstrap diode for reduced component count.
