NCP1421 |
Part Number | NCP1421 |
Manufacturer | ON |
Description | Pin Symbol Description 1 FB Output Voltage Feedback Input. 2 LBI/EN Low−Battery Detector Input and IC Enable. With this pin pulled down below 0.5 V, the device is disabled and enters the shutdown mode. 3 LBO Open−Drain Low−Battery Detector Output. Output is LOW when VLBI is < 1.20 V. LBO is high impedance in shutdown mode. 4 REF 1.20 V Referen. |
Features |
for various battery−operated applications. With all these functions on, the quiescent supply current is typically only 8.5 mA. This device is available in the compact and low profile Micro8t package. Features
• High Efficiency: 94% for 3.3 V Output at 200 mA from 2.5 V Input 88% for 3.3 V Output at 500 mA from 2.5 V Input • High Switching Frequency, up to 1.2 MHz (not hitting current limit) • Output Current up to 600 mA at VIN = 2.5 V and VOUT = 3.3 V • True−Cutoff Function Reduces Device Shutdown Current to typically 50 nA • Anti−Ringing Ring−Killer for Discontinuous Conduction Mode • High Ac. |
