1 / 14 page PWM Controlled Step‐Up DC/DC Controllers/Converters Series 437 4 ■General Description ■Features ■Applications NCMOS Low Power Consumption NOperating Voltage : 0.9V~10.0V NOutput Voltage Range : 2.0V~7.0V NOutput Voltage Accuracy: ±2.5% NSelectable Oscillator Frequency : 50kHz, 100kHz, 180kHz The XC6371 series are a group of PWM controlled step-up DC/DC converters. On-chip proprietary phase compensation and soft start-up circuits ensure excellent transient response and improved performance. Output voltage can be selected from 2.0V to 7.0V in 0.1V increments (accuracy: ±2.5%). Oscillator frequency is also selectable from three frequencies; 50, 100, and 180kHz (accuracy: ±15%). Every built-in switching transistor type enables a step-up circuit to be configured using only three external components; a coil, a diode, and a capacitor. External transistor versions are available to accommodate high output current applications. 5-pin packages, which are provided with either a CE (chip enable) function that reduces power consumption during shut-down mode, or a VDD pin (separated power and voltage detect pins) are available. SOT-89 small package. Operating (start-up) voltage range : 0.9V~10V Output voltage range : 2.0V~7.0V in 0.1V increments Highly accurate : Set-up voltage ±2.5% Oscillator frequency : 50kHz, 100kHz, 180khz (±15%) selectable Maximum output currents (Tr built-in) : Typ.100mA @ VIN=3.0, VOUT=5.0V .....Note(1) Highly efficient (Tr built-in) : Typ.85% @ VIN=3.0, VOUT=5.0V .....Note(1) Built-in switching transistor type and an external Tr type are available. Five-lead packaged units offer either Chip Enable or independent VOUT pin option. Phase compensation and soft start-up circuits built-in Small package : SOT-89 mini-power mold (3-pin, 5-pin) Note(1): Performance depends on external components and PCB layout.
