General Description

The UTC UC3837L is a high performance current mode PWM controller ideally suited for low standby power.

Low VDD startup current make the power reliable on startup design and a large value resistor could be used in the startup circuit to minimize the standby power.

At no load condition, the IC operates in power-saving mode for lower standby power, decreasing frequency for Higher conversion efficiency at light load condition.

Key Features

S.
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.
OLP with automatic recovery.
OTP and OVP ( in UTC UC3837L with latch shut down).
VDD clamp for higher security.
Programming BNO/Line OVP for higher security.
Fixed switch frequency 65kHz.
Gat.
