UC3800
Overview
The UTC UC3800 is a high performance current mode PWM controller ideally suited for low standby power. High voltage startup is implemented in UTC UC3800, which features with short startup time and no standby current.
- UTC proprietary frequency hopping technology for Improved EMI performance. * Power-saving mode for high light-load and standby efficiency * Soft Start * Dynamic peak current limiting for constant output power * Built-in synchronized slope compensation * OTP,OLP,OVP, LNO-OV, Brownout and VDD clamp for higher security
- Fixed switch frequency 65kHz * Gate output voltage clamped at 16V * Low start-up current * Cycle-by-cycle Current Limiting * Under voltage lockout (UVLO) * Few external components required
