DESCRIPTION
· The IXD3220/221 series are versatile step-down DC/DC controllers, requiring only a transistor, coil, diode, and two capacitors for a high-efficiency power supply up to 3A.
· Features a 0.9V (±1.5%) reference voltage for wide output voltage range via external resistive divider.
· Supports switching frequencies of 300 kHz, 500 kHz, and 1.0 MHz, enabling the use of small external components.
· IXD3220 operates in PWM mode, while IXD3221 automatically switches between PWM and PFM modes for efficiency across load conditions.
· Includes soft start (4 ms internal or externally set), UVLO, and integral protection against short circuits and overloads.
FEATURES
· Input voltage range: 2.8V to 16.0V.
· Output voltage externally set above 1.2V, with up to 3A output current.
· Oscillation frequencies: 300 kHz, 500 kHz, 1 MHz.
· PWM mode (IXD3220) or PWM/PFM auto-switching (IXD3221).
· Soft start: 4 ms internal (IXD3220A/221A) or externally set (IXD3220B/221B).
· Integral and short circuit protection.
· Compact packages: SOT-25, USP-6C.
APPLICATIONS
· Set-top boxes.
· Digital TVs.
· DVD/HDD recorders.
· Various portable equipment.
