XC9122 - Step-Up DC/DC Controller

Download the XC9122 datasheet PDF. This datasheet also covers the XC9120 variant, as both devices belong to the same step-up dc/dc controller family and are provided as variant models within a single manufacturer datasheet.

Description

XC9120/XC9121/XC9122 Series are PWM, PWM/PFM auto/external switching controlled step-up DC/DC converter controller ICs.

Since maximum duty ratio is as large as 93%, the series is the best for the applications used as high step-up ratios, such as the LCD panels and OLED.

Features

  • put Voltage Range : 0.9V ~ 6.0V Operating Voltage Range : 1.8V ~ 6.0V Output Voltage Range : 1.5V ~ 30V (externally set) Reference voltage 0.9V (±2.0%) Oscillation Frequency : 100kHz (±15%) Output Current : ≥80mA (VIN=3.6V, VOUT=15V).
  • Control : XC9120 (PWM) : XC9121 (PWM/PFM Automatic) : XC9122 (PWM/PFM Externally) High Efficiency : 85% (TYP. ) : (VIN=3.6V, VOUT=15V, IOUT=10mA).
  • Stand-by Function : ISTB=1.0A (MAX. ) Load Capacitors : Low ESR capacitor compatible Maximum Dut.

XC9120/XC9121/XC9122 Series ETR04009-005c Step-Up DC/DC Controller IC, MAXDUTY: 93% ☆Green Operation Compatible ■GENERAL DESCRIPTION XC9120/XC9121/XC9122 Series are PWM, PWM/PFM auto/external switching controlled step-up DC/DC converter controller ICs. Since maximum duty ratio is as large as 93%, the series is the best for the applications used as high step-up ratios, such as the LCD panels and OLED. In this series, even if it is a high step-up ratio, the output voltage stabilized at high efficiency can be obtained. With 0.9V (±2.0%) of reference voltage supply internal, and using external resistors, RFB1 and RFB2, output voltage can be set up freely within a range of 1.5V to 30V.
